Baselworld 2019: Rolex Sea-Dweller

Rolex is introducing an Oyster Perpetual Sea-Dweller in a yellow Rolesor version, combining Oystersteel and 18 ct yellow gold. This new watch brings 18 ct yellow gold to the Sea-Dweller range for the first time.

On its black dial, the name “Sea-Dweller” is inscribed in a yellow hue, echoing the colour of the 18 ct yellow gold. When the Sea-Dweller was updated in 2017, this lettering was in red, in reference to the original model. The light reflections on the case sides and lugs highlight the profile of the Sea-Dweller’s 43-mm Oyster case, which features a unidirectional rotatable bezel with a 60-minute graduated Cerachrom insert in black ceramic. This new version is equipped with calibre 3235, at the forefront of watchmaking technology. Like all Rolex watches, the new Sea-Dweller carries the Superlative Chronometer certification, which ensures excellent performance on the wrist.

The Sea-Dweller was designed in collaboration with the pioneers of professional deep-sea diving, who spent extended periods underwater. This ultra-resistant tool watch accompanied the first experimental underwater habitat programmes. It played a vital role in conquering the ocean depths thanks to its Oyster case, initially waterproof to a depth of 610 metres (2,000 feet), then, from 1978, to 1,220 metres (4,000 feet), and thanks to an important innovation patented by Rolex: the helium escape valve, fitted into the side of the watch case.
