Yacht-Master

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. Carrying the rich heritage that has bound Rolex and the world of sailing since the 1950s, this Professional watch provides a perfect blend of functionality and nautical style, making it equally at home on and off the water.

AN IMMEDIATELY RECOGNIZABLE BEZEL

The Yacht-Master is easily recognized by its bidirectional rotatable 60-minute graduated bezel made of 18 ct gold, 950 platinum or a technical ceramic (Cerachrom insert). The raised polished graduations and numerals stand out clearly against a matt background. This characteristic and functional bezel – which enables the wearer to calculate, for example, the sailing time between two buoys – plays a full part in creating the unique visual identity of the watch. The bezel can be turned with ease thanks to its knurled edge, which offers excellent grip.

LUMINESCENT CHROMALIGHT DISPLAY

The Yacht-Master offers great legibility in all circumstances, especially in the dark, thanks to its Chromalight display: the broad hands and hour markers are filled with a luminescent material emitting a long-lasting blue glow – lasting up to two times longer than traditional phosphorescent materials.

THE YACHT-MASTER, SUPERLATIVE CHRONOMETER

Like all Rolex watches, the Yacht-Master is certified as a Superlative Chronometer. This exclusive designation testifies 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, which exceed watchmaking norms and standards. These tests are carried out on the fully assembled watch, in order to guarantee superlative performance on the wrist. 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 COSC (Swiss Official Chronometer Testing Institute) – is tested a second time by Rolex after being cased, to ensure that it meets criteria for precision that are far more exacting than those for an official chronometer. The tolerance for the average rate of a Rolex Superlative Chronometer is of the order of −2/+2 seconds per day. Its precision is tested by Rolex using an exclusive methodology that simulates the conditions in which a watch is actually worn and is much more representative of real-life experience.

The Superlative Chronometer certification testing is carried out after casing using state-of-the-art equipment specially developed by Rolex. 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 that ensures the watches’ reliability, robustness, and resistance to magnetic fields and shocks.

THE OYSTER CASE, SYMBOL OF WATERPROOFNESS

The Yacht-Master’s Oyster case, guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of robustness and reliability. The characteristically shaped middle case is crafted from a solid block of particularly corrosion-resistant 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 winding crown – fitted with the Triplock (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, with a Cyclops lens at 3 o’clock for easy reading of the date, is made of virtually scratchproof sapphire. The waterproof Oyster case provides the Yacht-Master’s high-precision movement with optimal protection.

PERPETUAL 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. The architecture, manufacturing and innovative features of these movements make them exceptionally precise and reliable.

The oscillator 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.

Calibre 3235 features an optimized version of the blue Parachrom hairspring, manufactured by Rolex in an exclusive paramagnetic alloy, whilst calibre 2236 incorporates a Syloxi hairspring in silicon, patented and manufactured by the brand. Both hairsprings are insensitive to magnetic fields, offer great stability in the face of temperature variations and remain up to 10 times more precise than a traditional hairspring in case of shocks.

In calibre 3235, the blue Parachrom hairspring is fitted with a Rolex overcoil, guaranteeing its regularity in any position. The geometry of the Syloxi hairspring found in calibre 2236 offers the same level of performance.

Calibres 2236 and 3235 are fitted with a self-winding module featuring a Perpetual rotor, which ensures continuous winding of the mainspring by harnessing the movements of the wrist to provide a constant source of energy.

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

NEW-GENERATION MOVEMENTS

Calibre 2236 and calibre 3235 are new-generation movements entirely developed and manufactured by Rolex for a superlative level of performance. A consummate demonstration of Rolex technology, they offer fundamental gains in terms of precision, power reserve, resistance to shocks and magnetic fields, convenience and reliability.

The oscillator is fitted on high-performance Paraflex shock absorbers, designed and patented by Rolex, which increase the movements’ shock resistance.

Calibre 2236 features a paramagnetic nickel-phosphorus escape wheel and has a power reserve of approximately 55 hours.

Calibre 3235 incorporates the Chronergy escapement, patented by Rolex, which combines high energy efficiency with great dependability. Made of nickel-phosphorus, this escapement is also insensitive to magnetic fields. Thanks to the barrel architecture and the escapement’s superior efficiency, the power reserve of calibre 3235 extends to approximately 70 hours.

BRACELET AND CLASP: SECURE AND COMFORTABLE

The Yacht-Master 37 and Yacht-Master 40 in the Rolesium version (combining Oystersteel and 950 platinum) and the Everose Rolesor version (combining Oystersteel and 18 ct Everose gold) are fitted on a three-link Oyster bracelet, equipped with the Easylink comfort extension link. Developed by Rolex, this system allows the wearer to easily increase the bracelet length by approximately 5 mm, for additional comfort in any circumstance. A concealed attachment system ensures seamless visual continuity between the bracelet and case.

The Yacht-Master 37 in 18 ct Everose gold is equipped with the Oysterflex bracelet, developed and patented by Rolex. This technical bracelet singularly combines the robustness and reliability of a metal bracelet with the suppleness, comfort and aesthetics of an elastomer strap. It is composed of two flexible metal blades – one for each bracelet section – overmoulded with high-performance black elastomer.

The Yacht-Master 40 in 18 ct Everose gold and the Yacht-Master 42, made from 18 ct white gold, are fitted on an Oysterflex bracelet equipped with the Rolex Glidelock extension system. Developed and patented by the brand, this inventive toothed mechanism, integrated beneath the clasp, allows fine adjustment of the Oysterflex bracelet length by some 15 mm in increments of approximately 2.5 mm, without the use of tools.

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