Rolex Deepsea D-blue dial
Rolex uses 904L stainless steel for its steel watch cases. 904L steel is mainly used in the high technology, aerospace and chemical industries, where maximum resistance to corrosion is essential. A superalloy, 904L steel is extremely resistant and highly polishable. It maintains its beauty even in the harshest environments.
Commemorating James Cameron’s historic solo dive. From brilliant blue to bottomless black, its two-colour gradient dial celebrates one man’s journey to the deepest place on earth: the bottom of the Mariana Trench.
The Oyster bracelet is a perfect alchemy of form and function, aesthetics and technology, designed to be both robust and comfortable. It is equipped with an Oysterlock clasp, which prevents accidental opening, and an ingenious Glidelock, allowing fine adjustments of the bracelet without using any tools - and allowing it to be worn and comfortably over a diving suit.
The calibre 3235 is a new-generation movement entirely developed and manufactured by Rolex. This self-winding mechanical movement is at the forefront of the art of watchmaking. A consummate demonstration of Rolex technology, with 14 patents, it offers fundamental gains in terms of precision, power reserve, resistance to shocks and magnetic fields, convenience and reliability. It incorporates the new Chronergy escapement patented by Rolex, which combines high energy efficiency with great dependability. Made of nickel-phosphorus, it is also insensitive to magnetic interference.
Before they return to the open air, professional divers heading for the surface after a deep saturation dive must spend time in a decompression chamber, where they breathe a gas mixture containing helium. The tiny molecules of helium, an extremely light and non-volatile gas, infiltrate everywhere in the chamber, also penetrating the watch. During decompression, the helium is unable to escape from the waterproof case quickly enough, creating a pressure differential that could force the crystal out of the watch case. Rolex engineers created a gas escape valve fitted with a spring: it opens when the difference in pressure between the inside and outside of the watch reaches 3 to 5 bars, allowing the helium to escape, thereby protecting the watch.
