About this watch

Band: Steel (Oyster) Clasp: Steel (Oysterlock) Glass: Sapphire crystal Water Resistant: 390 Bar Rolex's deepest diving credentials trace back to 1960, when the experimental Deep Sea Special accompanied Jacques Piccard and Don Walsh to the bottom of the Mariana Trench aboard the bathyscaphe Trieste. James Cameron picked up that thread in 2012. He descended solo to the same depth, wearing a prototype Deepsea Challenge strapped to the outside of his submersible. The production Deepsea that resulted has been refined twice since. This piece is the third generation, reference 136660, introduced in 2022. Compared with its predecessor, the 126660, the bezel is slimmer and the date window larger. The patented Ringlock System that makes the depth rating possible remains unchanged. The case is Oystersteel, 44mm across and 17.7mm deep. It's pressure-resistant to 390 bar, or 3,900 metres.

This is a watch designed to actually dive. The dial is black, with broad hour markers in white gold surrounds filled with Chromalight, glowing blue for hours in the dark. The hands are the familiar Mercedes style. There is a date window at three, enlarged on this generation and magnified by the Cyclops lens. The crystal is sapphire, thick and domed, 5.5mm at its centre, and scratch-resistant. The bezel is black Cerachrom ceramic, unidirectional, and graduated to 60 minutes for timing a dive. The numerals are platinum-coated and resist fading. It's fitted to an Oystersteel Oyster bracelet, three-piece solid links, secured with a folding Oysterlock clasp. The Glidelock…
