Yema Flygraf - Automatic chronograph watch

Caliber 7750, circa 1975-1976.

At the crossroads of the sports chronograph and the aviation watch, this Yema Flygraf Automatic reflects the creative fervor that energized watchmaking in the 1970s.

Its particularly original dial architecture is paired with a circular slide rule integrated into the bezel. Inspired by instruments used by pilots, this device makes it possible to perform various calculations related to speed, time, or distance directly from the wrist. The mention “Patent Pending” on the dial highlights the innovative nature of this configuration at the time of its launch.

The watch is powered by the famous automatic Valjoux 7750 caliber, one of the most important chronograph movements in the history of Swiss watchmaking. Robust, reliable, and easy to service, it remains a benchmark in the world of mechanical chronographs to this day.

With its 40 mm diameter, assertive presence, and typically seventies aesthetic, this Flygraf remains one of the most original offerings from Yema’s production of that period.
