Rolex Sea-Dweller 16600 | Black Dial Saturation Dive Watch

A Legend Born From Pressure

Introduced in the late 1960s, the Rolex Sea-Dweller was created for the most demanding underwater professions, developed alongside commercial diving specialists including COMEX. Its breakthrough Helium Escape Valve answered a critical problem in saturation diving: the buildup of helium gas inside the watch during decompression, protecting the movement when returning to the surface.
