Omega 351 Description
The Omega 351 is the foundational workhorse of the brand’s “bumper” automatic movement family. Produced in large numbers from 1949-1954, it was the base time-only (sweep seconds), non-chronometer version used extensively in early Omega Seamaster models. Its robust bumper winding mechanism and reliable performance were instrumental in popularizing automatic watches for the brand. It operates at 19,800 bph.
