The Sea-Dweller was introduced in 1971 with ref. 1665; Rolex developed this model in collaboration with the French deep sea exploration company COMEX. The standard Submariner 5513 was the first watch to be fitted with Rolex's new invention, the gas escape valve. Later came the first Sea-Dweller, ref. 1665. Its first generation was inscribed "Sea-Dweller, Submariner 2000" in red. The second Sea-Dweller generation of ref. 1665 from 1973/4-1980 was simply signed "Sea-Dweller" in white; all were rated to 2000ft/610m. Ref. 1665 was replaced in 1980 by the ref. 16660 with quick-set date, sapphire crystal and improved "double gas-escape valve", which was rated to 4000ft/1220m. This reference was finally superseded in the mid 1990s by the ref.16600 with calibre 3135 "fast-beat" move.
