Made for Divers
First created in 1967, the Oyster Perpetual Sea-Dweller was designed for the pioneers of deep-sea diving, and became an integral tool for underwater engineering firm Compagnie Maritime d’Expertises. Taking from its predecessor’s known reliability, legibility and performance at extreme depths, the new Sea-Dweller 4000 is waterproof to a depth of 1,220 metres (4,000 feet) and features a 60-minute graduated, unidirectional Cerachrom bezel that enables divers to precisely and safely monitor their dive and compression times. A 40mm stainless steel case houses the self-winding calibre 3135 with date display, shown on a black satin-finished dial with white gold hour markers applied with Chromalight, which offer long-lasting luminescence. The watch also features Rolex’s helium escape valve.
