Rolex is introducing a new version of the Oyster Perpetual Yacht-Master, its emblematic nautical watch, for the first time in Everose Rolesor (a combination of 904L steel and 18 ct Everose gold) with a chocolate dial.

The new Yacht-Master 40 carries the Superlative Chronometer certification redefined by Rolex in 2015, which ensures singular performance on the wrist.

The Yacht-Master’s 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 that allows only Rolex watchmakers to access the movement. The winding crown, fitted with the Triplock triple waterproofness system and protected by a crown guard that is an integral part of the middle case, screws down securely against the case, offering 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 waterproof Oyster case provides optimum protection for the Yacht-Master’s high-precision movement.

The new Yacht-Master 40 is also available in steel and platinum combination.
