The Guba 28.1 watch movement is a manual wind mechanism with a sweep second function. It shares similarities with the ETA 901 movement, but the exact differences between the two are not well-documented. One possible variation could be the different bridge designs. The Guba 28.1 movement was commonly used in watches produced around the 1950s.
The Guba 28.1 features the following functions:
- Manual Winding
- Sweep second
