Comments about the data

Remarks
1972-1984, 575000
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.

family/generations:
1000: automatic, 17 jewels, date
1001: automatic, 20 jewels, date, chronometer
1002: automatic, 20 jewels, date
some improved details:
