Rolex Yacht-Master vs Yacht-Master II, What’s The Difference?

Rolex yacht-master vs yacht-master ii starting with the explorer ii in the 1970s, rolex has created a few model spin-offs over the years , where the second version is often larger or more technically advanced than the original. aside from the explorer ii, there’s the gmt-master ii, the datejust ii, and more recently, the yacht-master ii. but what exactly are the differences between the yacht-master and the yacht-master ii join us as we outline all the details as we compare the yacht-master vs yacht-master ii., origins: yacht-master vs yacht-master ii.

Rolex introduced the Yacht-Master in 1992 as an ultra-luxe sports watch with a nautical flair. The first reference in the collection was the Yacht-Master ref. 16628–a solid gold watch to emphasize the luxuriousness of the then-new Rolex model.

From its 40mm Oyster case to its rotating timing bezel to its Oyster bracelet, Rolex opted for 18k yellow gold for the very first Yacht-Master. Over the course of its history, the Yacht-Master collection welcomed other sizes and materials and today, it is one of Rolex’s most varied sports watch models.

The Yacht-Master II is a much younger Rolex watch , having made its debut in 2007. Featuring a regatta chronograph inside its large 44mm Oyster case, Rolex positioned the Yacht-Master II as a tool watch for professional racing sailors.

Like the original Yacht-Master, the first models of the Yacht-Master II were also 18k gold models but Rolex offered the choice of the white gold YM II ref. 116689 with a platinum bezel or the yellow gold YM II ref. 116688 with a blue ceramic bezel. Although the Yacht-Master II is still only available in one size, Rolex has added other metal options to the collection.

Design: Yacht-Master

Through the Yacht-Master is a varied collection , the defining traits of the watch include a water-resistant (to 100 meters) Oyster case, a Twinlock winding crown, a undirectional rotating bezel with raised numerals marked to 60 minutes, and the familiar Rolex sports watch dial layout with geometric lume-filled hour markers and Mercedes-style hands. The Yacht-Master is a time and date Rolex watch, therefore the dial is home to the date window at 3 o’clock accompanied by the customary Cyclops magnification lens protruding from the sapphire crystal.

Rolex has made the Yacht-Master in a number of case sizes throughout the decades: 29mm, 35mm, 37mm, 40mm, and 42mm. Rolex no longer makes 29mm or 35mm and currently only offers the latter three sizes.

Materials wise, Rolex originally made the Yacht-Master in yellow gold, stainless steel with a platinum bezel (dubbed Rolesium), and two-tone steel and yellow gold. These days however, Rolex no longer uses yellow gold in the Yacht-Master collection, opting for Everose gold (the brand’s proprietary rose gold alloy) instead. What’s more, Rolex recently added for the first time a Yacht-Master in white gold. Therefore, the Yacht-Master is now available in stainless steel with a platinum bezel, white gold, Everose gold with a black ceramic bezel, and two-tone steel and Everose gold.

While Rolex originally fitted the Yacht-Master exclusively with the three-link Oyster bracelet, in 2015, the brand debuted the black rubber Oysterflex bracelet. However, the Oysterflex bracelet is currently only available on the 37mm and 40mm Everose gold Yacht-Master and the 42mm white gold Yacht-Master.

Design: Yacht-Master II

The Rolex Yacht-Master II is one of the brand’s largest watches with a 44mm Oyster case, fitted with a Triplock winding crown, a pair of chronograph pushers, a Ring Command bezel, and an Oyster bracelet. It is also one of Rolex’s most complicated modern watches, complete with an innovative regatta chronograph with a programmable countdown feature (1 to 10 minutes) and a mechanical memory. Interestingly, rather than just a decorative element, rotating the Ring Command bezel is how you program the countdown function of the Yacht-Master II, which can be synchronized to the sequence of race start times during a regatta.

One of the most striking design elements of the Yacht-Master II is its dial design, which is unlike any other Rolex watch. The hour and minute hands are at the center while accompanied by the running seconds subdial at 6 o’clock. Arching above the center hands, from 8 o’clock to 4 o’clock, is the countdown display whereby the red arrow-tipped hand indicates how much time is left on the countdown. There’s also the central chronograph hand, which can flyback or fly-forward back to its starting position while in motion.

For the first decade of its production, the Yacht-Master II featured straight center hands and square lume-filled hour markers. However, as of 2017, Rolex switched to Mercedes-style hands and added a triangular hour marker at 12 and a rectangular hour marker at 6 to sit alongside the square ones.

The Yacht-Master II is available in a few different material versions: stainless steel with a blue Cerachrom bezel, yellow gold with a blue Cerachrom bezel, two-tone stainless steel and Everose gold with a blue Cerachrom bezel, and white gold with a platinum bezel.

Yacht-Master & Yacht-Master II References

Below is a comprehensive list of Rolex references for both the Yacht-Master and Yacht-Master II collections.

Yacht-Master II References

YM or YM II?

While they share the same name, it’s clear that the Yacht-Master and the Yacht-Master II are quite different. Yes, they’re both nautical-inspired Rolex sports watches, yet the first is smaller and more refined while the latter is larger, bolder, and more complex.

Whether you decide on the Rolex Yacht-Master or the Yacht-Master II depends largely on the size of what you’re looking for. If you want an oversized Rolex chronograph, then the Yacht-Master II may be right for you. If however, you are looking for a Rolex sports watch that is 40mm or smaller, then the Yacht-Master range is the better option.

Regardless of which model you pick, the Yacht-Master and the Yacht-Master II are fantastic Rolex watches inspired by a life at sea.

Overview of the Rolex Yacht-Master and Yacht-Master II

The Rolex Yacht-Master range encapsulates luxury and precision in a line of nautically inspired timepieces. Introduced in 1992, this Rolex watch borrows heavily from the Submariner series. The original Yacht-Master- the ref. 16628 with a 40mm Yellow Gold case, Cyclops lens over the date, triple lock crown, and Oyster bracelet- was modeled after the first ever Submariner- ref. 16610- which has a 40mm stainless steel case.

They both used the Caliber 3135 movement!

The tool watch gained traction with time, coming in various case, material, and bracelet options, as we shall see shortly. It’s no wonder it’s among Rolex’s most varied pieces in the Professional series.

Meanwhile, Rolex introduced the Yacht-Master II more than a decade later in 2007. It’s a watch tailored to the needs of professional sailors with its innovative regatta chronograph. 

Housed in a more robust 44mm Oyster case, it leveraged Rolex’s expertise in precision and functionality, offering a programmable countdown with mechanical memory for yacht racing. Distinguishing itself from its predecessor, it brought a new level of technical sophistication to the yachting world.

Design Characteristics

The Yacht-Master line portrays the typical design layout of Rolex sports watches, with an Oyster case (that’s water-resistant to 100m), a Twin-lock winding crown on the side of the case for setting the time and date and winding the movement manually, lume-filled Mercedes-style hands and hour markers, and a date function at three o’clock that’s amplified by a Cyclops magnifier lens on the crystal.

On the other hand, the Yacht-Master II takes on a more daring design, featuring a larger Oyster case (water-resistant to 100m) with a Triplock winding crown and chronograph pushers for operating the regatta chronograph, a busier dial with a programmable countdown feature (1 to 10 minutes), and a special Ring Command bezel that’s also present in Rolex’s Sky-Dweller collection .

Interestingly, the Yacht-Master II and Sky-Dweller are some of Rolex’s most complicated watches for now.

The Yacht-Master comes in various case options, namely 29mm (discontinued), 35mm (discontinued), 37mm (Rolex Yacht-Master ref. 268621), 40mm (Rolex Yacht-Master ref. 126622), and 42mm (Rolex Yacht-Master Oysterflex ref. 226659).

In terms of materials, Rolex has utilized several precious metals in the collection:

• Yellow Gold
• Stainless steel and Yellow Gold (Yellow Rolesor)
• Stainless steel with a Platinum bezel (Rolesium)
• Everose Gold (a patented proprietary Rose Gold alloy)
• Stainless steel and Everose Gold (Everose Rolesor)

In contrast, the Yacht-Master II is only available in a 44mm case size. It’s available in fewer material alternatives:

• Stainless steel with a blue ceramic Cerachrom bezel
• Stainless steel and Everose Gold with a blue ceramic Cerachrom bezel
• White Gold with a Platinum bezel (discontinued)
• Yellow gold with a blue Cerachrom bezel

Bezels 

The two watches have a bidirectional rotatable bezel that’s integral for tracking sailing time intervals. The difference comes in their designs.

The Yacht-Master has a bezel crafted from gold or platinum. This rotating bezel has raised numerals and 60-minute graduations. Plus, it operates independently from the watch’s inner mechanism.

The Yacht-Master offers a more noticeable Ring Command bezel with the ‘YACHT-MASTER II’ inscription and molded 1-10 numerals in varying colors depending on the materials used. The Yacht-Master II’s bezel is connected to the movement, and its wearers use it to operate the regatta chronograph function.

The watches’ dials are well-suited for their respective purposes. 

The Yacht-Master has a simpler dial design, with Mercedes-style hands and round/triangle/rectangle or gem-set hour markers. Rolex has used several luminous materials on these excellent luxury watches over the years:

• SuperLumiNova
• Chromalight

The Yacht-Master II has a more detailed and functional dial with slimmer hands decorated with Chromalight lume, a red arrow-tipped hand, a central chronograph hand, square-shaped hour markers, a countdown function with mechanical memory that gracefully curves from 8 to 4 o’clock, and a running seconds subdial at 6 o’clock.

The red arrow-tipped hand shows how much time is left in the countdown. Meanwhile, the central chronograph hand can fly back or fly forward to its starting position while in motion, and the countdown function allows skippers to sync it on the fly to match the official race countdown (it’s the first in the world, BTW).

Note: The Yacht-Master II had square hour markers and straight baton-shaped hands from 2007 to 2017. 

2017 welcomed several changes: an inverted triangle at 12 o’clock, a rectangular hour marker at six o’clock, and a Mercedes-style hour hand to offer more lume and enable easier differentiation from the minute hand.

Bracelets and Clasps

Rolex equips the Yacht-Master with Oyster and Oysterflex bracelets. The three-piece Oyster offers classic luxury and sturdy comfort and is finished with a high polish or brushed look. It also has a secure Folding Oysterlock safety clasp with Rolex Glidelock extension system that ensures the watch remains fastened around the wrist.

As for the Oysterflex bracelet , it’s a black strap crafted from a flexible Titanium and nickel alloy metal blade at its core and is clad in a high-density elastomer. It also boasts a tiered design that raises the timepiece away from the wrist and a Folding Oysterlock safety clasp with Rolex Glidelock extension system.

The YachtMaster II also features an Oyster bracelet, typically equipped with the Rolex Glidelock system, allowing fine adjustments and reflecting its more technical and sporty heritage.

Caliber Comparison

The Rolex Yacht-Master lineup features various movements, with the Yacht-Master 37mm housing a self-winding Caliber 2236 movement, the same movement used in Datejust 36 and Datejust 41 timepieces . It has 31 jewels, a 55-hour power reserve, and a 28,800vph frequency. 

Meanwhile, the 40mm and 42mm watches utilize the Caliber 3235, a well-respected automatic movement recognized for its reliability. This 31-jewel movement operates at 28,800 vibrations per hour (vph) and offers a power reserve of approximately 70 hours. 

In contrast, the Yacht-Master II is equipped with the self-winding Caliber 4161, a chronograph movement specifically developed for this model’s unique regatta countdown function. It has 48 jewels, a 72-hour power reserve, and a 28,800vph frequency.

Technical Details at a Glance

The following table highlights the specifications of both watches discussed above and more:

When comparing the Rolex Yacht-Master and the Yacht-Master II, consumers frequently have questions regarding their differences, pricing, availability, and rarity. The following subsections aim to address these common inquiries.

Almost Obscure: The Rolex Yacht-Master II 116689

Published by mike razak.

View all posts by Mike Razak

Rolex does not simply release watches on a whim. New models are rare, and updates to existing models are often minor, sometimes not even warranting an announcement. Regardless of timing or subtlety, everything The Crown does is met with scrutiny and drama. So, too, it was when the Yacht-Master II was released in 2007. The watch was met with mixed reactions: With an obscure complication that no one really asked for and the largest case in Rolex’s catalog, some thought it sullied the robust elegance of its forebear. Others rightfully praised its technical innovations. Fast forward more than a decade and the model seems to have won out: the Rolex Yacht-Master II 116689 seen here (and its sister references) remains in the Rolex catalog and is a favorite among those seeking a Rolex with a bit more panache and functionality than the standard Submariner.

When the original Yacht-Master was introduced in 1992, it was Rolex’s first entirely new model since the Sea-Dweller in 1967. The watch was an immediate hit with the seagoing elite, and has remained incredibly popular, with a variety of colorways and sizes released to satisfy demand.  Then, in 2007, the Yacht-Master II was released. Rolex spent over 35,000 hours designing the movement for the watch, which was designed to aid skippers in tracking the starting sequence of a regatta, including a novel integrated bezel and programmable countdown timer with memory function. Two models were part of the original release: the 116688 in solid 18kt gold with a blue ceramic bezel and the 116689 in 18kt white gold with an embossed platinum bezel.  

Design Details

At 44mm wide and 14mm thick, the Yacht-Master II features the largest production case Rolex offers. Despite its size, the watch is good to just 100m of water resistance—certainly sufficient for most aquatic adventures, but a subtle hint that Yacht-Master II is aimed at those who plan to remain aboard. The solid 18k white gold case and bracelet of the 116689 remain classic Rolex: polished throughout, with gentle curves, it gives way to the dual-finished Oyster bracelet, which features an Oysterlock clasp and Easylink 5mm extension for fine-tuned sizing. The patented Triplock crown and its guards maintain the aesthetic, with ringed chronograph pushers at its flanks. A white gold bezel—dubbed the Ring Command bezel for its added functionality—features a frosted platinum insert with embossed, polished numerals and model name. Protecting the dial is a sapphire crystal. 

Despite the watch’s functionality, Rolex has kept things extremely legible with a clean white dial. Square hour markers are applied and filled with the brand’s proprietary Chromalight lume. At 9 o’clock, the Crown logo is accompanied by the traditional Rolex dial text. At 6 o’clock, a running seconds subdial features a radial finished ring. The hands are all blued, with the hour and minute featuring lume; the minute hand has a cutout to allow for better timing legibility. In a large arc bounded by bright blue, the 10-minute regatta scale lines up perfectly with both the applied markers and the bezel. The countdown time is displayed by a bright red chronograph sweep hand and a lumed triangle minute hand.

To set the countdown timer, turn the Ring Command bezel 90 degrees counterclockwise, press the 4 o’clock pusher, and use the crown to set the desired interval (the triangle hand will snap back to 0 if pushed past 10). After rotating the bezel back, the watch’s pushers operate similarly to a normal chronograph. But Rolex has added two unique functions. When the timer is set, the initial countdown time is memorized: if the countdown is 7 minutes and needs to be restarted, stopping and resetting the timer will return it to 7 minutes. Equally impressive, the watch can be resynchronized to the official race countdown if necessary: pressing the reset pusher without stopping the timer will jump the timing hand to the nearest minute. 

Inner Workings

Powering the Rolex Yacht-Master II is the automatic Rolex 4161 caliber, based on the 4130 chronograph movement (seen in the Daytona). Comprising over 360 components, including 44 jewels, the movement beats at 28,800 vibrations per hour and delivers a robust 72 hours of power (a number of the constituent parts are so small, they require specialized micromanufacturing mastered in-house by Rolex). The watch is further equipped with Rolex’s Parachrom hairspring and Paraflex shock system, together delivering exceptional antimagnetism and shock resistance. As with all modern Rolex movements, the 4161 is certified to their Superlative Chronometer standards, accurate to -2/+2 seconds per day. 

Instead of the traditional chronograph functions of its base movement, the 4161 has been retooled to allow for use as a countdown timer. In conjunction with a vertical clutch, a column wheel extends through the main plate, allowing for the programmable countdown. Additional reworking has added instantaneous re-synchronization functionality and countdown memory; and as discussed above, the bezel is coupled to the movement to allow its use as a locking mechanism for the timer (though considering the bezel part of the movement might be a stretch). All of these decidedly niche features make for one of the most complicated Rolex calibers ever made. 

Versus the Competition

Watches and regattas have been linked for quite some time, and indeed many brands sponsor teams, races, or entire series. Omega and TAG Heuer have both released limited edition America’s Cup watches featuring countdown mechanisms. Panerai makes the Luminor 1950 Regatta Chrono Flyback and Ulysse Nardin has its Marine Regatta model. Of course, sometimes only a Rolex will do, in which case one can opt for the timing function of the Daytona, the Ring Command bezel of the Sky-Dweller, or the nouveau riche appeal of the original Yacht-Master. 

Personality

While the original Yacht-Master appealed to the owners of superyachts by providing a higher-end alternative to the Submariner, the Rolex Yacht-Master II 116689 builds on that appeal with the added bona fides of regatta timing functionalities. In the white gold execution, it’s perhaps best suited to the sailing enthusiast with who enjoys the occasional regatta and may even partake in one from time to time, but also likes a splash of luxury on the wrist and isn’t afraid to let others know.  

Final Thoughts

Be it as it may an undeniable piece of luxury sailing kit, the Yacht-Master II does what only a few Rolexes do: provides both the exceptional quality the brand is known for and unique functionality. For that alone, the model is well worth a look.

Yacht-Master II

THE SKIPPERS’ WATCH

The Oyster Perpetual Yacht-Master II is a unique regatta chronograph dedicated to both experienced sailors and yachting enthusiasts.

A PROFESSIONAL REGATTA CHRONOGRAPH

As in any contest of speed, precision and synchronization are of the essence in a regatta. The Yacht-Master II is equipped with a countdown that can be programmed from 10 to 1 minutes, allowing the wearer to precisely time and follow each race’s specific official starting procedure, which generally unfolds in three stages, marked by sound and visual signals. This flexibility is one of the major assets of the Yacht-Master II; its development was a considerable mechanical challenge. Furthermore, the programming can be mechanically memorized, which makes it possible to start a new countdown without having to reprogramme the watch, for example in the next leg or a subsequent regatta with identical countdown duration.

Once launched, the countdown can be synchronized on the fly to match the official countdown via the ‘fly-back’ reset function of the seconds hand and adjustment of the countdown minute hand to the nearest minute.

RING COMMAND SYSTEM

The countdown’s sophisticated functions were designed to be easily set and operated. The preliminary programming of up to 10 minutes is accessed, and then locked, via the rotatable bezel thanks to Ring Command, a system of interaction between the bezel, the winding crown and the movement, developed by Rolex. Its development, a feat of technical prowess, was made possible by the brand’s complete in-house mastery over the design and manufacturing processes, from the case and bracelet to the movement with its many components.

BEZEL WITH CERACHROM INSERT

The bidirectional rotatable bezel on the Yacht-Master II is equipped with a monobloc Cerachrom insert in blue ceramic. This patented insert is made of an extremely hard, virtually scratchproof ceramic whose colour is unaffected by ultraviolet rays. In addition, thanks to its chemical composition, the high-tech ceramic is inert and cannot corrode. The numerals and inscriptions are moulded in the ceramic and coloured with gold or platinum using a PVD (Physical Vapour Deposition) process.

CHROMALIGHT DISPLAY

The Yacht-Master II is an extremely legible watch in all circumstances and even in the dark thanks to the Chromalight display; the hour markers and hands are filled or coated with a luminescent material emitting a long-lasting blue glow – for up to two times longer than traditional phosphorescent materials.

THE YACHT-MASTER II, SUPERLATIVE CHRONOMETER CERTIFIED

Like all Rolex watches, the Yacht-Master II is covered by the Superlative Chronometer certification redefined by Rolex in 2015. This exclusive designation attests that every watch leaving the brand’s workshops has successfully undergone a series of tests conducted by Rolex in its own laboratories and according to its own criteria. These certification tests are carried out on the fully assembled watch, after casing the movement, guaranteeing superlative performance on the wrist in terms of precision, power reserve, waterproofness and self-winding. The Superlative Chronometer status is symbolized by the green seal that comes with every Rolex watch and is coupled with an international five-year guarantee.

The precision of every movement – officially certified as a chronometer by the Swiss Official Chronometer Testing Institute (COSC) – is tested a second time by Rolex after being cased, to ensure that it meets criteria for precision that are far stricter than those of the official certification. The precision of a Rolex Superlative Chronometer is of the order of −2/+2 seconds per day – the rate deviation tolerated by the brand for a finished watch is significantly smaller than that accepted by COSC for official certification of the movement alone.

The Superlative Chronometer certification testing is carried out after casing using state-of-the-art equipment specially developed by Rolex and according to an exclusive protocol that simulates the conditions in which a watch is actually worn and more closely represents real-life experience. The entirely automated series of tests also checks the waterproofness, the self-winding capacity and the power reserve of 100 per cent of Rolex watches. These tests systematically complement the qualification testing upstream during development and production, in order to ensure the watches’ reliability, robustness, and resistance to strong magnetic fields and to shocks.

THE OYSTER CASE, SYMBOL OF WATERPROOFNESS

The Yacht-Master II’s Oyster case, 44 mm in diameter and guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of robustness and reliability. The middle case is crafted from a solid block of Oystersteel or 18 ct gold. The case back, edged with fine fluting, is hermetically screwed down with a special tool that allows only certified Rolex watchmakers to access the movement. The Triplock winding crown, fitted with a triple waterproofness system, screws down securely against the case. It is protected by a crown guard that is an integral part of the middle case. The crystal is made of virtually scratchproof sapphire and benefits from an anti-reflective coating. The waterproof Oyster case provides optimal protection for the movement it houses .

PERPETUAL CALIBRE 4161

The Yacht-Master II is equipped with calibre 4161, a self-winding mechanical chronograph movement entirely developed and manufactured by Rolex. A consummate demonstration of technology, this movement offers outstanding performance, particularly in terms of precision, power reserve, convenience and reliability.

Calibre 4161 is based on the 4130 chronograph movement, which equipped the Oyster Perpetual Cosmograph Daytona until 2022. It is fitted with a traversing column wheel and vertical clutch for an instantaneous and extremely precise chronograph start.

The movement incorporates the blue Parachrom hairspring, manufactured by Rolex in a paramagnetic alloy. In addition to resisting strong magnetic fields, this hairspring offers great stability in the face of temperature variations as well as high resistance to shocks. It is equipped with a Rolex overcoil, ensuring the calibre’s regularity in any position.

The oscillator of calibre 4161 has a large balance wheel with variable inertia regulated extremely precisely via gold Microstella nuts. It is held firmly in place by a height-adjustable traversing bridge enabling very stable positioning to increase shock resistance.

Calibre 4161 is fitted with a self-winding system via a Perpetual rotor, which ensures continuous winding of the mainspring by harnessing the movements of the wrist to provide constant energy. It offers a power reserve of approximately 72 hours.

The Yacht-Master II’s movement will be seen only by certified Rolex watchmakers, yet it is beautifully finished and decorated in keeping with the brand’s uncompromising quality standards.

BRACELET AND CLASP, SECURE AND COMFORTABLE

The Yacht-Master II is available on a three-piece link Oyster bracelet that is equipped with a Rolex-designed, patented Oysterlock safety clasp, which prevents accidental opening. The bracelet is additionally fitted with the Easylink comfort extension link, developed by the brand. This system allows the wearer to easily increase the bracelet length by approximately 5 mm, for additional comfort in any circumstance.

Rolex Chronographs: Daytona vs. Yacht-Master II

The Daytona is, without a doubt, Rolex’s most famous chronograph model. However, it is sometimes overlooked that a Rolex does, in fact, manufacture another chronograph collection – the Yacht-Master II. While both are technically chronograph watches, they are actually very different timepieces, both inside and out. Today we will be comparing the brand’s duo of contemporary chronograph models, the Rolex Daytona vs. Yacht-Master II.

So, how do these two Rolex chronograph watches differ when it comes to their designs and functionality? Let’s find out as we review these stylish used Rolex watch models .

Origins: Daytona vs. Yacht-Master II

Rolex first unleashed the Cosmograph Daytona in 1963 as a chronograph dedicated to motorsports. However, as manually-wound models with 38mm cases, vintage Daytona watches are significantly different from the versions of today. It was only in 2000 that we saw the first iterations of today’s Daytona models; that is to say, 40mm watches that run on in-house automatic chronograph movements.

These editions of the Rolex Daytona collection carry six-digit reference numbers and are powered by the Caliber 4130. Prior to this generation, there were the five-digit Daytona models fitted with Rolex-modified, Zenith El Primero automatic movements, which were produced from 1988 until 2000.

In total, the Daytona utilizes three different generations of movements. First was the hand-wound generation, followed by the automatic Zenith generation, and then the automatic in-house Rolex caliber 4130. The collection has one of the most intriguing histories on the market, spanning decades and producing countless design variations, and even the famous Paul Newman Daytona that fetched one of the highest sums on the secondary market of nearly $18 million.

On the other hand, the Yacht-Master II is a relatively new Rolex model, having made its debut in 2007. What’s more, when it was released, the Yacht-Master II was Rolex’s largest watch, sporting a 44mm case. As its name implies, the Rolex Yacht-Master II was developed for the sailing crowd, rather than the automobile racing crew. In addition to its over-the-top case size and design, the Yacht-Master II was also the brand’s most complex watch (until the introduction of the Sky-Dweller in 2012), equipped with a regatta chronograph, complete with mechanical memory and fly-back functionality for facilitated synchronization.

Design: Daytona vs. Yacht-Master II

The Daytona’s 40mm case comes fitted with a pair of screw-down chronograph pushers flanking its screw-down winding crown. This is to keep any moisture out of the watch, ensuring its 100-meter water resistance. The fixed bezels of the Daytona watches – crafted from either metal or Cerachrom (ceramic) – are engraved with a tachymeter scale (except for the gem-set bezel editions), while the dials house a trio of subsidiary registers.

In true Rolex fashion, there are plenty of different dial colors and index styles to choose from. Material options within the six-digit Daytona family include stainless steel, yellow gold, white gold, Everose gold, two-tone steel and yellow gold, and platinum. Most Daytona models come with metal Oyster bracelets however, there are some gold Daytona watches that are presented on black rubber Oysterflex bracelets as well. Rolex previously manufactured leather-strap versions but they are no longer in production.

In direct contrast to the Daytona’s classic looks and restrained proportions, the Yacht-Master II is proudly big, bold, and badass. Its bezel – either in bright blue Cerachrom (ceramic) or platinum – sits on the 44mm case and is emblazoned with the “YACHT-MASTER II” name, along with numbers 1 – 10. The white dial with red and blue accents offers three distinct areas for three readings: the center hands, the 10-minute countdown display, and the running seconds sub-dial.

Early editions of the Yacht-Master II included straight hour and minute hands until around 2017, while current versions have the familiar Mercedes-style hands. The hour markers received a small upgrade from blue to white gold surrounds to match the hands. Additionally, Rolex replaced the square hour marker at 12 o’clock with an inverted triangle and the marker at 6 o’clock with a slightly elongated baton hour marker. Material choices of the Yacht-Master II include yellow gold, white gold (with a platinum bezel), stainless steel, and two-tone Everose gold and steel. Additionally, all Yacht-Master II watches come with matching metal Oyster bracelets.

Calibers and Functionality: Daytona vs. Yacht-Master II

Manufactured entirely in-house, the Daytona’s Caliber 4130 has been heralded by many watch enthusiasts as one of the most reliable and robust automatic chronograph movements on the market. One of its defining features is the use of a vertical (rather than lateral) clutch to activate the chronograph. This not only permits the chronograph hand to run smoothly without any signs of “jittering,” but also allows the chronograph function to run for a long time with no influence on the Daytona’s precision. Thanks to Caliber 4130, the Daytona features a chronograph hand accurate to within 1/8 of a second, a 30-minute counter at 3, a 12-hour counter at 9, a small seconds register at 6, and a power reserve of 72 hours.

When Rolex launched the Yacht-Master II in 2007, inside the watch was the Caliber 4160, which was then upgraded to Caliber 4161 in 2013. While these in-house chronograph calibers are based on the Caliber 4130, they are much more complex in terms of functionality. Rolex maintains that the Caliber 4160/4161 was the result of over 35,000 hours of development.

Most intriguing, the bezel on the Yacht-Master II is not just for show. Instead, turning it allows the user to flip through what functions of the watch to set. And one of these functions includes a programmable countdown timer (from 1 – 10 minutes), which also memorizes the desired setting t when you reset the timer. So, if you love a seven-minute jammy egg or a four-minute brew, then your Yacht-Master II is there for you.

The central chronograph hand also has flyback functionality, which means that you can reset it back to zero with the press of a single button while it is in motion. Additionally, just like its base caliber, the Cal. 4160/4161 also has a 72-hour power reserve.

While both chronographs have countless everyday applications, they cater to two totally different niches. The Daytona, with its motorsport roots, was initially developed to help the wearer record various stats while driving, such as speed, distance traveled, and elapsed time. On the other hand, the Yacht-Master II was inspired by regatta and features a race countdown mechanism.

How to Use The Bezels on Daytona vs. Yacht-Master II

The Daytona bezel is fixed, so its primary function relies on the chronograph movement. To activate the chronograph, press the top pusher above the crown. The chronograph seconds hand will start to race around the dial. The top pusher will also stop the chronograph while the bottom pusher resets it to zero. For example, to measure speed, simply activate the chronograph by pressing the top pusher. Once you’ve driven a mile, stop the chronograph by pressing the top pusher again. The chronograph hand will point to the corresponding speed on the Tachymeter bezel.

The Yacht-Master II bezel is connected to the movement and it is often referred to as a “Ring Command Bezel.” To use the programmable regatta countdown, you first need to unscrew the crown and rotate the bezel counterclockwise 90 degrees. Then, press the bottom pusher and turn the crown clockwise to move the arrow hand to the desired 10-minute count-down increment. Once the bezel is rotated back to its original position and the crown is screwed back into the case, you can press the top pusher to start or stop the countdown. The chronograph seconds hand will begin to move around the dial, once every minute. The famous flyback and fly-forward functionality is engaged by pressing the bottom pusher, sending the arrow hand backwards or forwards to the nearest minute in the countdown.

Side-by-side, these two Rolex chronographs look nothing alike. The Daytona offers traditional chronograph styling and functionality, while the Yacht-Master II is more aggressively designed and offers a niche complication in the form of a regatta chronograph. So, which one would be your pick?

Luxury rules at the moscow yacht show.

by Maria Sapozhnikova

The windy Russian autumn weather might be a little bit tricky for sailing, but it doesn’t stop brave yachtsmen from all over the world from flocking to Russian capital in the beginning of September when the Moscow Yacht Show commences. The main Russian Yacht exhibition gathers professional and amateur yacht lovers together under the wing of The Royal Yacht Club.

This year it took place for a fourth time already. The exhibition is considered the principal event on the sporting and social calendar. The Moscow Yacht Show 2010 united in one area three of the largest Russian yachts distributors: Ultramarine, Nordmarine and Premium Yachts.

A wide range of yachts were on display for a week. An exhibition showcased yachts both from Russian manufacturers and world famous brands: Azimut, Princess, Ferretti, Pershing, Riviera, Doral, Linssen, etc.

It was a real feast for seafarers as visitors of the show had a unique chance not only to take a look at the newest superyachts before they hit the market, but also to evaluate their driving advantages during the test drive. The show provided an excellent opportunity for yacht enthusiasts to choose and buy a new boat for the next season.

The event started with the grandiose gala evening. It included grand dinner, the concert and professional awards ceremony for achievements in Russian yachting industry. The guests also enjoyed the annual regatta.

Special guest Paolo Vitelli, Azimut Benetti Group president, opened the evening.

Next year organizers assured guests they would bring more yachts, the scale of which will even make oligarch Roman Abramovich envious. Sounds very promising indeed.

Prioritization Methods and Techniques – Part 2: MoSCoW Method

In my previous article, Prioritization Methods and Techniques - Part 1: Why Prioritize and the Kano Model , I talked about the need to prioritize and the Kano model as a prioritization method. In this second article in the series on prioritization methods and techniques, I will discuss the MoSCoW method.

The MoSCoW method is a highly widespread prioritization method which was popularized by Dynamic Systems Development Method (DSDM). The term MoSCoW has nothing to do with the capital of Russia. It is an acronym derived from the first letter of each of four prioritization categories – Must have, Should have, Could have and Won’t have.[1] The two “O” are added to make the word pronounceable.

Must have: This category contains requirements or features that are absolutely mandatory. Those are fundamental to the system (being a product or a service). If any of them are neglected, the system will certainly not work or will have no value for the customer.

Should have: These features are important, ideally, we should have them for the system to work correctly. If they are not there, a workaround may be possible, but it can be costly or cumbersome. Yet, they are not mandatory and therefore do not have the highest priority. Simply put, they don’t have much impact on delivery success right now, though they must be implemented soon enough (after the “must-haves”).

Could have: These are useful additions (often small-scale improvements) that add tangible value. These are “nice-to-have” requests. In general, they do not take considerable resources, but they are not essential to implement either. Their absence won’t affect almost anything, or at least wouldn’t impact the release negatively.

Won’t have (sometimes also known as “would like to have, but not this time”): These items are not worth the investment (of time, money, energy) and are unlikely to make the cut (at least not in the near future). These requirements are of the lowest importance and can be easily omitted (definitely considered out of scope for the first release) or rescheduled for future releases.

When prioritizing requirements in a project, DSDM recommends no more than 60% effort for “must-haves” requirements and a sensible pool of “could-haves”, usually around 20% effort (see Figure 1 below). Anything that is higher than 60% effort for the “must-haves” poses a risk to the success and predictability of the project, unless the environment and the used technology are well understood, there are minimal external risks/dependencies and the team is experienced and well established. Note that we are talking about a balance based on estimated effort of requirements (i.e. the expected time it takes to implement the prioritized features) and not total number of requirements. When calculating effort for a specific timeframe (e.g. first release), “won’t haves” are excluded, as they are considered out of scope for this timeframe.[2]

Figure 1: Balancing priorities using the MoSCoW prioritization technique (recommendation by DSDM[2])

Practical example

Let’s take a simple practical example. How can you categorize the features required to manufacture a child’s bicycle?

Must have: two wheels ; a frame

Should have: brakes for safe stopping; pedals; ability to adjust the saddle to accommodate growth; safety cover for the chain; stabilizers or the ability to fit them when needed (the last two features can also be classified as “could-haves” depending how essential they are for the child/parents)

Could have: bell or horn to alert others in proximity; attractive color of the bike; front suspension; Presta valves for inflating tires

Won’t have: valve caps to cover the tires valve; Bluetooth bike speaker

Even though it may seem strange not to have the pedals and the brakes in the “must have” category, in reality they are not mandatory for a child’s bike. By definition a bike is two-wheeled transportation device, so it must certainly have two wheels and a frame to link the wheels together, but everything else is subject to discussion and negotiation. For example, small kids can learn to ride a bike by simply using their feet, so no pedals and brakes are really needed. This simple example also shows that there is often a disconnect between expectations and requirements. People often have high level of expectations, but high expectations are different from must-have requirements which are mandatory and non-negotiable.

Let’s now look at the advantages and disadvantages of the MoSCoW method.

Pros of MoSCoW

• Simplicity. The MoSCoW method is one of the simplest prioritization techniques. It does not require searching for detailed data or making complicated calculations. So, it is easy to master and use because it is based on simple principles. Using this prioritization scheme in a product management context promotes mutual understanding between product people (product managers and product owners) and stakeholders. It is also a great method to resolve conflicts and to bring stakeholders to consensus. Prioritizing work using MoSCoW is fast and transparent.
• Agility for flexible scheduling and implementation. Since this prioritization method has no strict time limits for the implementation, except for the “must-have” category (items there should always go first and be implemented as soon as possible), it allows for flexible implementation timeframes per feature. Therefore, a team can easily adjust feature deliveries or releases on favorable terms based on agreement with customers/stakeholders.

Cons of MoSCoW

The MoSCoW technique is very simple, but such simplicity comes with some pitfalls.

• The technique lacks a clear consistency of implementation and lacks specific planning per feature. Even though priorities can be easily and quickly set, the MoSCoW method prioritizes the backlog items in four categories (in a similar fashion to the Kano model, covered in my previous article, which also prioritizes features in different categories), so it does not introduce any sequencing of features/backlog items and lacks specific planning. This makes it quite challenging for product people to decide on the exact priority of a feature compared to another one within the same category. At the end of the day, this drawback might put the entire release at risk.
• MoSCoW classification rules can be subjective and this creates imbalance between the absolutely required (must have or mandatory) and slightly desirable. Often, the blurred lines between categories make it hard to decide in which category a feature should go into, specifically when we talk about “must-have” and “should-have” lists. But it is sometimes also the case between “should-haves” and could-haves”. This happens due to the subjectivity of requirements. Therefore, features or stories allocated to the different categories should be approached with great thought and care and the chosen categorization should be agreed with (or well explained to) all stakeholders.

When to use the MoSCoW method

The MoSCoW method is probably the simplest and most widespread prioritization scheme for new product development, and more specifically for small products. But as we saw above, this technique also has its disadvantages and is not always effective. For instance, if you have a complicated backlog with many time-sensitive releases, consider choosing other prioritization method or complementing MoSCoW with another more accurate or comprehensive technique.

On the other hand, it is quite reasonable to use MoSCoW when prioritizing work for small (and not too complex) products, which does not have many technical limitations. The MoSCoW requirements help product people and teams take a strategic, orderly approach to prioritization. This method is great for avoiding wasted time, arguments and misdirection.

In my next article I will talk about the Eisenhower matrix. Meanwhile, if you want to know more about prioritizing using the MoSCoW method, please feel free to contact me.

To be represented by Premium Yachts, Ferretti Yachts and Riva , two prestigious brands of the Ferretti Group, will be present at the Moscow International Boat Show 2013, displaying motor yacht Ferretti 530 as well as Riva Iseo yacht tender.

Luxury motor yacht Ferretti 530

Luxury yacht Ferretti 530 was very keen to undertake in collaboration once again with AYT – Advanced Yacht Technology, Ferretti Group Engineering Division and Studio Zuccon International Project . The compact dimensions, 16 meters long and almost 5 meters wide, allow the 530 yacht to deliver grand Italian luxury and cruising immersed in such comfort until now unheard of in a yacht of this size.

Ferretti 530 yacht boasts three revolutionary innovations: the full beam master cabin with chaise longue and two large open view windows that make it a real suite at sea level bathed in light, tones and the natural essences of teak. Moving the galley from the center to the aft section creates a unique open space that includes the saloon, galley, cocktail bar and the dining area, the cockpit area continues thanks to the tilting window. The roll bar free sky lounge and the spoiler allow the 530 a sporty appearance combined with elegantly formal lines.

Ferretti 530 Yacht - Interior

Riva , the iconic Ferretti Group brand, presented a new model at the historical Lake d’Iseo shipyards in July 2011. Featuring elegance and ease of transportation as its distinctive characteristics, Iseo superyacht tender , a 27 foot runabout, is destined to become a must-have for those who love cruising on both lakes and the sea, and, most importantly, design enthusiasts. It is also perfect for anyone wishing to enhance their yacht with an exclusive tender that will never go unnoticed.

Riva Iseo superyacht tender

Due to its ease of manoeuvrability and size, Iseo yacht tender is also ideal as a tender for large yachts. Innovative and elegant, it can also guarantee comfort in bad weather conditions. Besides the electrohydraulic bimini top, it was also designed with a waterproof, automobile-style soft top which protects those on board against water and the wind during cruising.
