The Landeron 189 watch movement, which was in use around 1945, offers a manual winding mechanism and includes a sub-second function. Variations in balance staffs have been observed, but the differences are generally small and can be adapted. Some recorded designations, such as 175, 176, 179, 184, 196, 204, 232, and 235, may refer to different bridge shapes, although specific disparities are unclear.
The Landeron 189 features the following functions:
- Manual Winding
