Omega Seamaster Bumper


Built for sea, town, and country, the world of vintage Omega Seamasters is as iconic and versatile as any. They were elegant enough to take around town, but durable enough to be worn in the fields and in water. This early iteration of the Seamaster was manufactured in 1952 and represents a milestone in Omega’s watch-making legacy. The caliber 354 movement that is housed in this watch is a “bumper” movement, which winds the watch by bouncing a bumper back and forth off a pair of springs on opposite sides of the watch. Decorated with a unique metallic dial and beautiful lugs, this Seamaster is worth a second look.

Note: this watch is paired with an after-market strap. 

Condition: The watch has been serviced in 2020 and inspected by a certified watch maker and is running very well.
