Comments about the data

Remarks
Girocap combined settings for escapement wheel
indirectly driven minute allows a very big balance
These movements are obviously a joint venture of Doxa, Ebel, Eberhard, Favre-Leuba, Girard-Perregaux, Juvenia, and Zodiac.
Bestfit mentions the calibres Felsa 4035 and 4036 as equivalent, but as these are not contained in any other register, it is uncertain who actually produced them.

family:
13: stem winding
14: backwinder

Example, year: signature; shock device
ca. 1965: 59, Ebel, Fab Suisse; Incabloc
(Ebel 59)

Not for Sale!
