Notes
1955
wheels beryllium bronze
The low quantity of movements from this family, compared with the pedecessors and succesors, indicate that they were produced hardly longer than one year. Dispite this two variants of the manual wind gear and two balances were produced in parallel, and one may believe that all was just an experiment.
