The watch that conquered the deep

The Sea-Dweller and Rolex Deepsea are ultra-resistant divers’ watches engineered by Rolex for deep-sea exploration. 

Waterproof to a depth of 4,000 feet (1,220 metres) for the Rolex Sea-Dweller, launched in 1967, and 12,800 feet (3,900 metres) for the Rolex Deepsea unveiled in 2008, they are the ultimate manifestation of Rolex’s leadership in divers’ watches and the result of decades of collaboration with diving professionals.

In 2014 Rolex released a special version of the model, the Rolex Deepsea with a D-blue dial, to commemorate James Cameron’s historic solo dive to the bottom of the Mariana Trench, some 11,000 metres deep. From twilight blue to bottomless black, its two-colour gradient dial celebrates one man’s journey to the deepest place on Earth.

  • The Sea-Dweller’s 60-minute graduated, unidirectional rotatable bezel enables divers to safely monitor their dive and decompression times. It is equipped with a patented black Cerachrom bezel insert manufactured by Rolex in a virtually scratchproof and corrosion proof ceramic whose colour is unaffected by ultraviolet rays. The graduation is coated via PVD (Physical Vapour Deposition) with a thin layer of platinum.

  • No other watch is engineered like the Rolex Deepsea. Waterproof to an extreme depth of 3,900 metres (12,800 feet), this new-generation divers’ watch benefits from exclusive innovations developed by Rolex to exceed the most exacting demands of professional divers.

  • For excellent legibility in dark conditions, the sleek black dial features large Chromalight hour markers and hands filled with luminescent material that emits a long-lasting blue glow.

  • Early saturation divers experienced a troublesome phenomenon that affected their watches during the decompression phase in hyperbaric chambers filled with breathing mixes composed largely of helium.

  • Helium molecules are so tiny that they can slowly penetrate the watch case through the gaskets, so the pressure inside the watch equalizes with the pressure inside the habitat. However, during a diver’s decompression process to be slowly brought back to normal atmospheric pressure, the gas is unable to escape from the waterproof case sufficiently quickly. 

  • To address this issue, Rolex invented and patented the gas escape valve for watches, a one-way valve which safely allows the helium trapped in the watch to be released at a given pressure during decompression, while preserving the tight waterproofness of the Oyster case.

  • In 1960, U.S. Navy Lieutenant Don Walsh and Swiss oceanographer Jacques Piccard forever raised the bar for marine exploration by piloting the bathyscaphe Trieste to the deepest point in the world’s oceans, Challenger Deep in the Mariana Trench.

  • On 26 March 2012, film-maker and National Geographic Explorer-in-Residence James Cameron descended into the Mariana Trench in his submersible, making the deepest-ever solo dive.

  • 2012 - The Oyster Perpetual Rolex Deepsea Challenge
    Setting the record for the deepest diving watch in the world
  • It was the first manned dive to the deepest part of the Trench, known as Challenger Deep, since the pioneering two-man Trieste expedition of 1960. Only one passenger joined both voyages: a Rolex watch.

    James Cameron also took the 1960 Deep Sea Special watch produced by Rolex with him in the cockpit, as a tribute to the pioneers of the Trieste and as a symbolic connection between two eras of exploration.

Deepsea Challenge, the ultimate diver

Manufactured in RLX Titanium and equipped with the exclusive helium escape valve and Ringlock System, the Oyster Perpetual Deepsea Challenge is the ultimate diver’s watch. With a waterproofness guaranteed up to 11,000 metres, it is capable of accompanying divers in any environment: during freedives, submersible dives or in hyperbaric chambers.
