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

This is a rare early type bumper automatic model with roulette 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 with roulette numbers that have changed over time with texture are all examples of the unique vintage taste of this era.
