Omega Seamaster Automatic Bumper Black Dial Gold Cap Mens Vntage Watch 2637 automatic Title: Vintage Omega 30T2 WindingPLEASE NOTE: [Introducing Omega's "Half Rotor" in the 1950s . Omega's early automatic half rotor. A half rotor winds the mainspring by making a 3 4 turn instead of a 360 rotation of the rotor. When the rotor rotates, a spring is installed on the opposite side as a shock absorbing device, and when the rotor and spring collide, a characteristic "knock" sound and shock are transmitted. For this reason, the half rotor is also called the "bumper type"].
