The Omega 1108 watch movement features a rotor placed out of center and a winding gear that is integrated within the movement. With a detached manual wind and the first screw balance (later replaced by a ring balance), this movement achieved a remarkably thin design for its time. It should be noted that for Ocean Star models, the split stem cannot be detached by pulling the crown, but rather detaches when the movement is turned to the right angle. The movement incorporates various functions including automatic winding, sweep seconds, and a date function that is set by changing 20-24 hours. Additionally, it includes the features of sweep seconds, automatic winding, and Incabloc shock protection. This movement was typically utilized around the year 1963.
