Comments about the data
1968-1973, 370000 (1000-1002)
The automatic gear is integrated into the movement, instead of attaching it to a manual-wind calibre as usual.
Together with indirectly driven minute and second this leaves in the center space for a rugged rotor bearing, despite the low profile.
