Rolex diving line has been around for decades, focused on a narrow mission statement: go deeper than almost any other watch on the wrists of proffesional divers, without compromising on style. Now, Rolex is unveiling the new Rolex Oyster Perpetual Deepsea.
In 1960, Rolex made watchmaking history when it joined the bathyscaphe Trieste on an unprecedented dive to the deepest known point in the world's oceans.
Crewed by brave Swiss oceanographer Jacques Piccard and U.S. Navy Lieutenant Don Walsh, The Trieste was carrying an experimental Rolex Deep Sea Special wristwatch when it reached the bottom of the Mariana Trench in the Pacific Ocean – at record depth of 10,916 metres.
On 26 March 2012, the expedition's submersible piloted by James Cameron, famous filmmaker and explorer, descended 10,908 metres to reach Challenger Deep, the deepest point in the world's oceans.
Designed to resist extreme underwater pressure, the Oyster Perpetual Deepsea meets the exacting requirements of professional divers. It features a 44 mm case with redesigned lugs and sides and a broader Oyster bracelet, as well as a correspondingly adapted Oysterlock folding safety clasp.
The case of the new Rolex Deepsea is also equipped with a helium escape valve, developed and patented by Rolex in 1967, which works to protect diver's watches created for the deep. It allows excess pressure built up in a watch case to escape during a diver's decompression in a hyperbaric chamber.
A special hyperbaric test tank was developed in partnership with COMEX, renowed French company specializing in underwater engineering and hyperbaric technologies. And, in deep-sea diving, absolute reliability and security are of the essence. Every single Deepsea is tested to ensure its waterproofness to a depth of 3,900 metres with an additional safety margin of 25 percent. This professional divers' watch, is equipped for the first time with calibre 3235, at the forefront of watchmaking technology.
The new Rolex Deepsea is made of Oystersteel, and sports a D-blue dial with a deep-blue to pitch-black gradient. It's Oyster case was developed to ensure phenomenal resistance to pressure without compromising the size and thickness of the watch.
The unidirectional rotatable bezel of the Rolex Deepsea is fitted with a 60-minute graduated Cerachrom insert in black ceramic that allows divers to monitor their underwater and decompression time for their safety. This Rolex-patented insert, made of an extremely hard and corrosion-resistant ceramic, is virtually scratchproof, and its colour is unaffected by ultraviolet rays.
The Rolex Deepsea's Oyster bracelet is equipped with an Oysterlock safety clasp that prevents accidental opening and a double extension system that allows the watch to be worn comfortably over a professional diving suit up to 7 mm thick – the patented Glidelock system allows fine adjustment in approximately 2mm increments for a total of some 20mm, while the Fliplock extension link extends the Deepsea bracelet by 26 mm. Like all Rolex watches, the new Rolex Deepsea carries the Superlative Chronometer certification, which ensures singular performance on the wrist.
The new Rolex Deepsea is equipped with calibre 3235, a new-generation movement entirely developed and manufactured by Rolex. A consummate demonstration of Rolex technology, at the forefront of the art of watchmaking, this self-winding mechanical movement offers fundamental gains in terms of precision, power reserve, resistance to shocks and magnetism, convenience and reliability.
It incorporates the Chronergy escapement patented by Rolex, which combines high energy efficiency with great dependability. Made of nickel-phosphorus, it is also insensitive to magnetic interference. Manufactured by Rolex in an exclusive paramagnetic alloy, the Parachrom hairspring is up to 10 times more precise than a traditional hairspring in case of shocks.
