OYSTER PERPETUAL SEA-DWELLER
A legend among divers’ watches, the first Sea-Dweller models were guaranteed to a depth of 2,000 feet to accompany the pioneers of deep-sea diving. Updated in 2017 for its 50th anniversary, and now waterproof to 4,000 feet, the Sea-Dweller features a arger 43 mm case and calibre 3235, a new-generation movement at the forefront of watchmaking technology. It is, of course, equipped with the helium escape valve that allows excess pressure built up in the watch case to escape during a diver’s decompression phase in a hyperbaric chamber, as patented by Rolex in 1967. Above or below water it’s an icon for the wrist.
