Rolex is unveiling the new Oyster Perpetual Rolex Deepsea. 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. 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. This dial was launched in 2014 on a commemorative version of the watch in tribute to the a class="lien_externe" href='/en/The-Rolex-Deepsea-Challenge-2012-watch-To-the-deepest-reaches-of-the-oceans-No_9045.htm' data-href='9045' data-site='LCDM' data-title='La Cote des Montres: The Rolex Deepsea Challenge 2012 watch - To the deepest reaches of the oceans ' data-marque='Rolex' data-codeMarque='4524'>DEEPSEA CHALLENGE expedition. On this journey, partnered by Rolex and the National Geographic Society, film-maker and explorer James Cameron descended 10,908 metres (35,787 feet) to the ocean’s deepest point, located in the Mariana Trench.

Like all Rolex watches, the new Rolex Deepsea carries the Superlative Chronometer certification, which ensures singular performance on the wrist.

A divers’ watch designed for the deep, the Rolex Deepsea is waterproof to 3,900 metres (12,800 feet). Its Oyster case was developed to ensure phenomenal resistance to pressure without compromising the size and thickness of the watch. The resulting Ringlock System, a patented case architecture, allows the Rolex Deepsea to with-stand the colossal pressure exerted at extreme depths. The Ringlock System is composed of three elements: a domed 5.5 mm-thick sapphire crystal, a high-performance nitrogen-alloyed stainless steel ring, positioned inside the middle case of the watch, and a case back in Oystersteel and grade 5 titanium. The Triplock winding crown, equipped with three seals, screws down securely against the case, completing the waterproofness system and guaranteeing watertight security akin to a submarine’s hatch.

The case of the Rolex Deepsea is also equipped with a helium escape valve, developed and patented by Rolex in 1967, which works to protect divers’ watches created for the deep. It allows excess pressure built up in the watch case to escape during a diver’s decompression phase in a hyperbaric chamber.

In deep-sea diving, absolute reliability and security are of the essence. Each Rolex Deepsea must therefore undergo the necessary waterproofness tests required for divers’ watches. To this end, a special hyperbaric test tank was developed in conjunction with COMEX (Compagnie Maritime d’Expertises, the world-renowned French company specializing in underwater engineering and hyperbaric technologies). Every single Rolex Deepsea is tested to ensure its waterproofness to a depth of 3,900 metres with an additional safety margin of 25 per cent.


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 numerals and the graduations are moulded in the ceramic and coloured with platinum using a PVD (Physical Vapour Deposition) process. The bezel’s knurled edge offers excellent grip when manipulating the bezel to set dive time, even when wearing gloves.

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. The oscillator, the true heart of the watch, has a blue Parachrom hairspring. 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. It is also fitted with a Rolex overcoil, ensuring its regularity in any position.

Calibre 3235 is equipped with a self-winding module via a Perpetual rotor. Thanks to its new barrel architecture and the escapement’s superior efficiency, the power reserve of calibre 3235 extends to approximately 70 hours.


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 diving suit up to 7 mm thick. Using a toothed panel located under the clasp cover, the patented Rolex Glidelock system allows fine adjustment of the bracelet length in approximately 2 mm increments up to around 20 mm, while the Fliplock extension link extends the Rolex Deepsea bracelet by 26 mm. Both extension systems and the clasp have been adjusted to fit the watch’s broader bracelet.

Like all Rolex watches, the Rolex Deepsea is covered by the Superlative Chronometer certification rede ned by Rolex in 2015. This exclusive designation testifies that each watch has successfully undergone a series of tests conducted by Rolex in its own laboratories according to its own criteria, which exceed watchmaking norms and standards. The certification applies to the fully assembled watch, after casing the movement, guaranteeing superlative performance on the wrist in terms of precision, power reserve, waterproofness and self-winding. The precision of a Rolex Superlative Chronometer is of the order of −2 /+2 seconds per day, or more than twice that required of an official chronometer.

The Superlative Chronometer status is symbolized by the green seal that comes with every Rolex watch and is coupled with an international five-year guarantee.

In 1960 – 52 years before the DEEPSEA CHALLENGE expedition – 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 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 on 23 january 1960, at a record depth of 10,916 metres (35,814 feet).

On 26 March 2012, the expedition’s submersible piloted by James Cameron descended 10,908 metres (35,787 feet) to reach a class="lien_externe" href='/en/The-deepest-place-on-earth-Rolex-makes-history-Again-James-Cameron-makes-first-ever-successful-solo-dive-to-Mariana-Trench-No_9064.htm' data-href='9064' data-site='LCDM' data-title='La Cote des Montres: The deepest place on earth, Rolex makes history.
