In the 1970s, Yema introduced the Wrist Master watch, reflecting the innovative trends of the time. Designed for professional divers and adventurers, it was known for its strong build and accurate timekeeping.

This Yema dial was heavily oxidized. The design was honor of the Chinese year of the dragon, done with a more aggressive and expressive graffiti style to expand the design across the rest of the dial but without covering it too much.

In Chinese culture the red dragon symbolizes good fortune and happiness.
