The ETA 1144 watch movement features a ratchet on the dial side and a crown mechanism with a rocker bar. In some versions with a date function, the early click spring may be somewhat difficult to access. However, this issue was later addressed by relocating the click spring. Additionally, the movement has rounded corners to facilitate its application in round cases. The ETA 1144 movement is manually wound and supports both sweep seconds and non-sweep seconds variations. It was commonly used around 1945.
