The Landeron 56 watch movement, produced around 1980, incorporates a unique design with separately driven train and hand gears by the barrel. This design enables a low profile and provides room for a larger balance. However, its implementation requires precise and shake-free gears due to the complex coupling between the second and minute hands. The movement offers manual winding and a sweep second function.
The Landeron 56 features the following functions:
- Manual Winding
- Sweep second
