Yacht-Master

THE WATCH OF THE OPEN SEAS

The Oyster Perpetual Yacht-Master, the emblematic nautical watch, embodies the privileged ties between Rolex and the world of sailing that stretch back to the 1950s.

Launched in 1992, the Yacht-Master was designed specifically for navigators and skippers. Embodying the rich heritage that has bound Rolex and the world of sailing since the 1950s, this Professional-category watch provides a perfect blend of functionality and nautical style, making it equally at home on and off the water.

ROTATABLE BEZEL WITH RAISED GRADUATIONS

The Yacht-Master is easily recognized by its bidirectional rotatable 60-minute graduated bezel made entirely from precious metal – Everose gold or platinum – or fitted with a Cerachrom insert in high-technology ceramic. The raised, polished graduations and numerals stand out clearly against a matt background. This characteristic and functional bezel – which enables the wearer to read time intervals, for example, the sailing time between two buoys – plays a full part in creating the visual identity of the watch. The bezel can be turned with ease thanks to its knurled edge, which offers excellent grip.

CHROMALIGHT DISPLAY

The Yacht-Master offers great legibility in all circumstances, even in the dark, thanks to its Chromalight display: the large hour markers and broad 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, SUPERLATIVE CHRONOMETER CERTIFIED

Like all Rolex watches, the Yacht-Master 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 apply to 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 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 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’s Oyster case, 37 mm, 40 mm, or 42 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, RLX titanium 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 an integral crown guard. The crystal, with a Cyclops lens at 3 o’clock for easy reading of the date, 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.

CALIBRES 2236 AND 3235

Yacht-Master models are equipped with calibre 2236 (Yacht-Master 37) or calibre 3235 (Yacht-Master 40 and Yacht-Master 42), self-winding mechanical movements entirely developed and manufactured by Rolex. Consummate demonstrations of technology, these movements carry a number of patents. They offer outstanding performance, particularly in terms of precision, power reserve, convenience and reliability.

Calibre 2236 is fitted with the patented Syloxi hairspring in silicon, manufactured by the brand. 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. Its geometry, which is also patented, ensures the movement’s regularity in any position. Calibre 2236 includes a paramagnetic nickel-phosphorus escape wheel.

Calibre 3235 incorporates the patented Chronergy escapement, made of nickel-phosphorus, which combines high energy efficiency with great dependability and is also resistant to strong magnetic fields. This movement is fitted with 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 these two calibres has a 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. The oscillator is also mounted on the Rolex-designed, patented high-performance Paraflex shock absorbers, further enhancing the movements’ shock resistance.

Calibre 2236 and calibre 3235 are equipped 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. Calibre 2236 offers a power reserve of approximately 55 hours, while the power reserve of calibre 3235 extends to approximately 70 hours thanks to its barrel architecture and the escapement’s superior efficiency; moreover, since 2023, its oscillating weight has been fitted with an optimized ball bearing.

The Yacht-Master’s movements will be seen only by certified Rolex watchmakers, yet they are beautifully finished and decorated. Since 2023, calibre 3235 has also been marked with the words ‘Chronometer Perpetual’ and ‘Superlative Adjusted’ engraved respectively on the oscillating weight and on the bridges.

BRACELET AND CLASP: SECURE AND COMFORTABLE

The Rolesium versions (combining Oystersteel and platinum) and the Everose Rolesor versions (combining Oystersteel and Everose gold) of the Yacht-Master 37 and the Yacht-Master 40, as well as the Yacht-Master 42 in RLX titanium, are fitted on a three-piece link Oyster bracelet, equipped with the Easylink comfort extension link. This system, developed by Rolex, allows the wearer to easily increase the bracelet length by approximately 5 mm, for additional comfort in any circumstance. On the Yacht-Master 42 in RLX titanium, the bracelet includes ceramic inserts – designed by Rolex and patented – inside the links to enhance its flexibility and longevity.

The Yacht-Master 37 and Yacht-Master 40 in 18 ct Everose gold, as well as the Yacht-Master 42 in 18 ct yellow or white gold, are fitted on an Oysterflex bracelet, composed of two flexible, curved metal blades – one for each bracelet section – overmoulded with high-performance black elastomer. This Rolex-designed, patented bracelet is furnished with the Rolex Glidelock extension system, also developed by the brand and patented. On the Oysterflex bracelet, this inventive toothed mechanism has six notches of approximately 2.5 mm, allowing the bracelet length to be effortlessly adjusted up to some 15 mm.

The Oyster and Oysterflex bracelets on the Yacht Master models are equipped with an Oysterlock safety clasp, designed by Rolex and patented, which prevents accidental opening.
