A Rolex Sea-Dweller stainless steel automatic wristwatch, reference 1665, serial number 6.7XX,XXX, featuring a black dial with date aperture and unidirectional rotating dive bezel. Introduced in 1967 for professional saturation divers, the Sea-Dweller was developed in collaboration with commercial diving specialists to withstand extreme underwater pressures while incorporating Rolex’s patented helium escape valve, allowing trapped gases to safely vent during decompression. The reference 1665 is among the model’s most celebrated vintage iterations and remains highly sought after for its historical importance, robust construction, and enduring association with professional diving. Accompanied by a Rolex Submariner booklet and Rolex factory service literature.
