Key features

A classic digi-mech design, unusually round dial and crystal. The chrome plated case has slight wear to it, though is still sturdy and shiny, and the patently 1970’s style fume dial is in perfect condition. The watch has an hour and minute wheel, with the minute wheel displaying the time in 5 minute increments.

NOTE: It is strictly recommended that you do not move the hour discs backwards, and only move them forwards to avoid any maladjustment of the jump-hour springs.

The Yema Sous-Marine was tested and used by the Jacques Yves Cousteau Calypso team, after which it became a super popular watch model in France. This watch is from the same 70’s, an era when electronic digital indication was introduced.
