The Dugena 3901 watch movement is a manual wind movement that was likely produced around the 1940s. It shares minor differences with the Peseux 140 and 290 movements, and it is possible that the differing designations (140 through 147) are simply related to variations in bridge shapes. Further details about the specific differences between these movements are unknown.
The Dugena 3901 features the following functions:
- Manual Winding
