Rolex introduced a new version of its nautical watch at this year’s Baselworld, the Oyster Perpetual Yacht-Master, for the first time in a combination of 904L steel and Everose gold, with a warm-toned chocolate dial.
Sporty but sleek, the new Yacht-Master 40 is strongly characterised by its bidirectional rotatable 60-minute graduated bezel in Everose gold with polished raised numerals and graduations which stand out clearly against a matt, sand-blasted background. This bezel is not just decorative and can be used, as an example, to calculate the sailing time between two buoys.
The use of gold and steel on the same watch has been a signature feature of Rolex since 1933, when the brand registered the Rolesor name for this combination of metals.
On the Yacht-Master, Everose gold is used for the bezel as well as for the centre bracelet links while the winding crown, the middle case and the outer bracelet links are made of 904L steel.
With its middle case crafted from a solid block of steel and the fluted case back hermetically screwed down with a special tool that allows only Rolex watchmakers to access the movement, the Yacht-Master 40 is waterproof to a depth of 100 metres / 330 feet.
The winding crown is fitted with the Triplock triple waterproofness system and protected by a crown guard that is an integral part of the middle case.
The chocolate dial with sunray finish is enhanced by pink gold applied hour markers and hands which are treated with Chromalight for long-lasting luminescence in poor light conditions. The sapphire crystal features a Cyclops lens at 3 o’clock for easy reading of the date.
The Yacht-Master 40 is equipped with calibre 3135, a self-winding mechanical movement beating at 28,800 vph and offering 48 hours of power reserve. It features the patented blue Parachrom hairspring which is insensitive to magnetic fields. According to Rolex, this kind of hairspring 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.
The new Yacht-Master 40 carries the Superlative Chronometer certification to testify that the fully assembled watch has undergone a series of tests conducted by Rolex in its own laboratories to guarantee the highest standards in terms of precision (−2/+2 seconds per day), power reserve, waterproofness and self-winding.
