The Omega 1119 mechanical watch movement, which was used during the period of 1975-1983, features a service-friendly modular design. The movement incorporates an automatic module with a gear extending into a free section opposite to the stem. This design allows for a low total height, despite the modular construction. The movement offers various functions, including automatic winding, a sweep second hand, the option of operating without a second hand, a quickset date feature, and a hack feature.
