The Rolex Oyster Perpetual Date Sea-Dweller is a line of diver's watches manufactured by Rolex, with an underwater diving depth rating of 610 metres (2,000 ft) for the vintage models and up to 3,900 metres (12,800 ft) for the most recent Sea-Dweller DEEPSEA model.
The Rolex Oyster Perpetual Sea-Dweller Submariner 2000 (2000 ft = 610 m) that became available in 1967 was developed from the Submariner for the Comex S.A. industrial deep-sea diving company by increasing crystal thickness and was produced in several variations. It had a depth rating of 610 metres (2,000 ft) and its Rolex reference number was 1665. Most Sea-Dweller watches incorporate a helium escape valve for saturation diving.
In 2008, Rolex introduced an updated Sea-Dweller model, named the Rolex Oyster Perpetual Date Sea-Dweller DEEPSEA. Its reference number is 116660. With an official depth rating of 3,900 metres (12,800 ft), the Sea-Dweller DEEPSEA represented in its launch year the most water resistant mechanical watch in serial production.
