Given that the Rolex Sea-Dweller is waterproof up to a depth of 4,000 feet, we reckon it’s pretty aptly named; a special edition of this same watch was even created to commemorate James Cameron’s solo dive to the bottom of the Mariana Trench. The Sea-Dweller first debuted in 1967 as a purpose-built watch for deep-sea divers. It featured a more pressure-resistant case than anything else on the market at the time, and a helium escape valve to avoid the glass cracking when coming back to the surface.

At the depths this watch is capable of you’ll need a trustworthy mechanism for a watch at those depths, so Rolex went with the 3235 movement. This particular movement offers enhanced protection against magnetic interference and uses Chronergy escapement with a power reserve of 70 hours.

The new edition of the famed Sea-Dweller has stayed at a comfortable 43mm wide and sports a two-tone look thanks to its 18 karat gold and “Rolesor” steel. This is the first time a Sea-Dweller has been offered up in gold.

The unidirectional rotating bezel has 60-minute gradations on the black Cerachrom insert. The crown features Rolex’s Triplock waterproof system, which combines with the original helium valve.

You can add the Rolex Sea-Dweller in two-tone gold and stainless steel to your diving paraphernalia for USD$16,050 later this year.
