The Cyma Tavannes 777 watch movement, used around 1965, features Girocap combined settings for the escapement wheel and an indirectly driven minute that allows for a very large balance. These movements were developed as a collaboration between notable brands including Doxa, Ebel, Eberhard, Favre-Leuba, Girard-Perregaux, Juvenia, and Zodiac. Although Bestfit refers to the Felsa 4035 and 4036 calibres as possible equivalents, there is uncertainty regarding their actual manufacturer. The movement is manually wound and includes additional functions without further elaboration.
The Cyma Tavannes 777 features the following functions:
- Manual Winding
