The Guba 25 watch movement, which was used during the period from 1961 onwards, shares some similarities with the Aurore-Villeret 120, Bulova 6AH, and FHF 120 calibres. There is contradicting information regarding interchangeability in different movement registers. However, the design details of the Bulova calibres suggest a potential connection with Aurore-Villeret. This movement offers manual winding and a sweep second function.
The Guba 25 features the following functions:
- Manual Winding
- Sweep second
