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"].
