The new 40 mm version of the Oyster Perpetual YACHT-MASTER in ROLESIUM, a combination of steel and platinum, also benefits from the latest Rolex innovations in terms of the ergonomics, comfort and reliability of the bracelet, clasp and bezel. Its emblematic bidirectional rotatable graduated bezel in 950 platinum with raised numerals has been entirely rethought to include a new, even more robust rotation system.
The CHROMALIGHT display, an exclusive Rolex feature, ensures long-lasting luminescence for exceptional legibility in the dark. This new YACHT-MASTER features a case in 904L stainless steel on an OYSTER bracelet with a new generation OYSTERLOCK safety clasp. The elegant solid-link bracelet offers much-appreciated comfort and ease of use. It also includes the EASYLINK rapid extension link, an ingenious system that conveniently allows the wearer to lengthen the bracelet by about 5 mm for added comfort in any circumstance. With its stunning blue sunray finish dial, the new model can generate waves among passionate sailors and adventurers.
The bidirectional rotation system on the bezel of this new YACHT-MASTER is based on a 120-position notched ring and a trigonal spring providing a constant torque in both directions, ensuring minimal wear and highly precise manipulation. The bezel with raised graduations contributes greatly to the unique identity of the model and its functions.
Made entirely of 950 platinum, with polished graduations standing out against a sand-blasted finish, it can be easily set to time a period of up to 60 minutes – for example the sailing time between two buoys – or to provide a reminder of elapsed time. The dial harbours large CHROMALIGHT hour markers and hands filled with luminescent material that emits a long-lasting blue glow, offering exceptional legibility in the dark.
The YACHT-MASTER’s 40 mm OYSTER case, guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of robustness. The characteristically shaped middle case is crafted from a solid block of particularly corrosion-resistant 904L steel. The fluted case back is hermetically screwed down with a special tool exclusive to Rolex watchmakers. The winding crown, fitted with the patented 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 synthetic sapphire. The waterproof OYSTER case ensures optimal protection for the YACHT-MASTER’s high-precision movement.
The YACHT-MASTER is equipped with calibre 3135, a self-winding mechanical movement entirely designed and manufactured by Rolex. Like all PERPETUAL movements, the 3135 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. Its architecture, like that of all OYSTER watch movements, makes it singularly precise and reliable. The oscillator, the true heart of the watch, has a blue PARACHROM hairspring patented and manufactured by Rolex in an exclusive alloy. Insensitive to magnetic fields, the PARACHROM hairspring offers great stability when exposed to temperature variations and remains up to 10 times more precise than a traditional hairspring in case of shocks.
The new YACHT-MASTER is fitted with a solid-link OYSTER bracelet in 904L steel with a new-generation OYSTERLOCK safety clasp, both simple to manipulate and including a security system to prevent accidental opening. Developed and patented by Rolex, this elegant solid-link bracelet offers remarkable comfort and ease of use. It also features the ingenious EASYLINK rapid extension system that allows the wearer to easily increase the bracelet length by approximately 5 mm, for additional comfort in any circumstance.
