THE WATCH THAT CONQUERED THE DEEP
A legend among divers’ watches, the Oyster Perpetual Sea-Dweller was created in 1967 to accompany the pioneers of deep-sea diving. A technical divers’ watch waterproof to a depth of 1,220 metres (4,000 feet), the Oyster Perpetual Sea-Dweller is a new version of the model designed in 1967 for the pioneers of professional deepsea diving. Updated for its 50th anniversary in 2017, the Sea-Dweller features a 43 mm case and the new calibre 3235, at the forefront of watchmaking technology. It is, of course, equipped with one of the inventions that contributed to its stature: the helium escape valve, patented by Rolex in 1967. This ingenious safety valve regulates the pressure accumulated in the watch case during the decompression phases of deep-water saturation dives.
