Rolex Oyster Perpetual Yacht-Master 40, Gem set version

Dressed in an 18 ct Everose gold case with a black gloss finish dial, the new gem set version of Rolex’s emblematic nautical watch Oyster Perpetual Yacht-Master 40 features a bidirectional rotatable bezel adorned with multicolour sapphires, green tsavorites, and a triangular diamond at 12 o’clock. Waterproof, precise and reliable, the Yacht-Master 40 embodies the privileged ties between Rolex and the world of sailing that stretch back to the 1950s. 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.
The Yacht-Master 40’s Oyster case is guaranteed waterproof to a depth of 100 metres The characteristically shaped middle case of watch 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 water-proofness system, the screw down crown provides watertight security. 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.
The Yacht-Master 40 is ftted on an Oysterflex bracelet, developed and patented by Rolex. This technical bracelet combines in a singular way the robustness and reliability of a metal bracelet with the flexibility, comfort and aesthetics of an elastomer strap. At its core lies a superelastic metal blade overmoulded with high-performance black elastomer, a material that is particularly resistant to environmental effects and very durable. The Oysterflex bracelet is also fitted with an 18 ct Everose gold Oysterlock safety clasp that prevents accidental opening.
 Like all Rolex watches, the Yacht-Master 40 is covered by the Superlative Chronometer certification redefined by Rolex in 2015. This exclusive designation testifies that the watch has successfully undergone a series of tests conducted by Rolex in its own laboratories according to its own criteria, which exceed watchmaking norms and standards. The certification applies 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 precision of a Rolex Superlative
Chronometer after casing is of the order of −2/+2 seconds per day, or more than twice that required of an official chronometer.
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.
