Notes
1973-1980
ratcet wheel beryllium bronze
smallest ever industrial manufactured automatic movement, regarding the volume (diameter and height)
This movement consists as most automatics of a manual-wind base movement and an automatic module screwed on it. But here a rather small train leaves some space for parts of the automatic module. So the total height could be remarkably reduced (cf. Fig.3, 4).
