Rolex: Yacht-Master 4010 April 2017
Rolex is introducing a new gem-set version of the Oyster Perpetual Yacht-Master 40. In 18 ct Everose gold with a black gloss finish dial, it features a bidirectional rotatable bezel adorned with multicolour sapphires, green tsavorites, and a triangular diamond at 12 o’clock.
The Yacht-Master 40’s Oyster case, guaranteed waterproof to a depth of 100 metres, is a paragon of robustness. Its characteristically shaped middle case is crafted from a solid block of 18 ct Everose gold. Its fluted case back is hermetically screwed down with a special tool that allows only Rolex watchmakers to access the movement. The winding crown is protected by a crown guard that is an integral part of the middle case. Fitted with the Triplock triple waterproofness system, the crown screws down securely against the case, providing watertight security akin to a submarine’s hatch. The crystal, with a Cyclops lens at 3 o’clock for easy reading of the date, is made of virtually scratchproof sapphire.
The Yacht-Master 40 is equipped with calibre 3135, a self-winding mechanical movement entirely developed and manufactured by Rolex. Its architecture, manufacturing quality and innovative features make 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 in the face of temperature variations and remains up to 10 times more precise than a traditional hairspring in case of shocks. A Rolex overcoil ensures its regularity in any position. Calibre 3135 is equipped with a self-winding module via a Perpetual rotor and offers a power reserve of approximately 48 hours.
This version is equipped with the innovative, elastomer Oysterflex bracelet developed and patented by Rolex.
Like all Rolex watches, the new Yacht-Master 40 carries the Superlative Chronometer certification redefined by Rolex in 2015, which ensures singular performance on the wrist.
