| Notes | 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.
