Return To ShopThe ETA 2391 watch movement, manufactured around 1965, features Girocap combined settings for the escapement wheel and an indirectly driven minute that enables a large balance. The movement is a result of a collaborative effort among renowned brands including Doxa, Ebel, Eberhard, Favre-Leuba, Girard-Perregaux, Juvenia, and Zodiac. While Bestfit mentions the equivalence of calibres Felsa 4035 and 4036, the actual producer remains uncertain as these calibres are not documented in any other register. This movement operates as a manual wind backwinder and offers additional functions.
The ETA 2391 features the following functions:
