Omega 353 Description

The Omega 353 is a “bumper” automatic from the early 1950s, adding a date window complication to the sweep-seconds design of the Cal. 351. Used in Seamaster “Calendate” models, this non-chronometer workhorse featured the family’s characteristic bumper winding system and 19,800 bph beat rate. The date is non-quickset, requiring the hands to be moved past midnight to advance.
