Rolex unveils the Oyster Perpetual Deepsea Challenge. This NEW divers' watch is waterproof up to 11,000 metres (36,090 feet), dwarfing the Rolex Deepsea, which presented in 2008, can resist the pressure exerted at 3,900 metres (12,800 feet).
Made of RLX titanium, a grade 5 titanium that has been developed by Rolex, the new watch is 30% lighter than the experimental model attached to the manipulator arm of James Cameron’s submersible on his historic 10,908-metre (35,787 feet) descent into the Mariana Trench on 26 March 2012.
The Deepsea Challenge is the culmination of Rolex’s expertise in divers’ watches. It includes all the major innovations developed by the brand over many years: the Ringlock system, a patented case architecture that enables the watch to withstand extreme pressure; the helium escape valve, which allows surplus gas to escape from the watch during a diver’s decompression phase in a hyperbaric chamber, reducing the pressure inside the case which could otherwise damage the watch; the Triplock crown, with three sealed zones; and the Chromalight display, whose long-lasting luminescence provides exceptional legibility.
To test the waterproofness of each Deepsea Challenge, Rolex specially developed, in partnership with Comex (Compagnie Maritime d’Expertises), an ultra-high-pressure tank capable of reproducing a test pressure equivalent to that exerted by water at a depth of 13,750 metres (45,112 feet).
The Deepsea Challenge is truly a milestone with the unprecedented depths that it can go to, representing an invitation to expand yet further the horizons of the deep.
