1940s Omega Stainless Steel Cal.28.10 Bumper Automatic Silver Two-tone Dial

This is a rare early type bumper automatic model with silver two-tone dial.

This is a rare half-rotor bumper automatic model before the full-rotor automatic models were born, and the unique mechanical sound of "con, con, con" is unique to the bumper type. The unique water-resistant case with metal O-rings on the snap-on back cover, and the silver two-tone dial that has changed over time with a rich texture, make this a gem of vintage taste unique to this era.
