The Sonceboz 99 H4.1 GENERATION 1 watch movement is a manual wind movement with a sub second function. It features variations with both sweep seconds and non-sweep seconds. The period of its usage is estimated to be around 1928. The movement is characterized by a stem mechanism without a setting-lever spring. It is worth noting that while the base plate of this calibre is known to be used for the higher Felsa 184, there are also older variants without a setting-lever spring and newer variants with a setting-lever spring from other Felsa calibres. The relation to the known Sonceboz 99 H4.1 GENERATION 1 new was confirmed by the dimensions of the staff and stem.
The Sonceboz 99 H4.1 GENERATION 1 features the following functions:
- Manual Winding
- Sub Second
- Sweep seconds and non-sweep seconds variations
