Comments about the data

Remarks
1975-1978
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:
2930: 21 jewels, date
2940: 21 jewels, day, date
2950: 17 jewels, date
2960: 17 jewels, day, date

Example, year: signature; shock device
1976: 19653082, Tissot, Swiss; Incabloc
