A Short History of the Diver's Watch
The modern diver's watch emerged in the early 1950s, when naval frogmen needed a reliable way to track remaining air time underwater.
Its defining features — a rotating bezel to mark elapsed minutes, a screw-down crown to keep water out, and high-contrast luminous markers — were all solutions to a specific, life-or-death problem.
Depth ratings climbed over the following decades as case-sealing technology improved, but the essential layout of a diver's watch has changed remarkably little since those first military-issue pieces.
