A few years ago, Rolex unveiled a new version of its nautical watch, the Oyster Perpetual Yacht-Master, for the first time in a combination of 904L steel and stellar gold with a warm-toned chocolate dial. The new Yacht Prestige 40 features a bi-directional rotating 60-minute graduated stellar gold bezel with polished raised numerals and indexes that stand out against a matte sandblasted background. This bezel is not only decorative but can also be used to calculate the sailing time between two buoys. 
The use of gold and steel on the same watch has been a signature feature of copy Rolex since 1933 when the brand registered the Rolesor name for this metal combination. In the Yacht Masters collection, stellar gold is used for the bezel and central bracelet links, while the winding crown, middle case, and outer bracelet links are made of 904L steel.
The middle case is made from a single block of steel, the fluted caseback is sealed and screwed down with a special tool so that only Rolex replica watches have access to the movement, and the Yacht-Master 40 is water-resistant to 100 meters/330 feet.
The winding crown is equipped with a Triplock triple water-resistance system and is protected by a crown guard integrated into the middle case.
The chocolate-colored dial has a sunburst pattern, and the rose gold hour-markers and hands are Chromalight-treated for long-lasting brilliance in low light conditions. The sapphire crystal has a Cyclops lens at 3 o’clock for easy reading of the date.
The Yacht-Master 40 is equipped with the caliber 3135, a self-winding mechanical movement that beats at 28,800 vibrations per hour and provides a 48-hour power reserve. It has a patented blue Parachrom hairspring that is insensitive to magnetic fields. According to Rolex, this hairspring is extremely stable in the face of temperature variations and remains 10 times more accurate than a conventional hairspring when subjected to shocks.
The new Yachtmaster 40 comes with a Super Chronometer certification, proving that this fully assembled watch has undergone a series of tests conducted by replica Rolex in its own laboratories to guarantee the highest standards in terms of precision, power reserve, water-resistance, and automatic winding. In all aspects, it is really one of the most popular Rolex watches among all.
