I got a Felca watch in a friend’s batch to take a look at. Felca is the Felca Watch SA, founded on July 12th, 1943 in Grenchen – Switzerland. Felca is parts of Titoni watches nowadays.
It didn’t run well but it’s a NOS piece with the original labels still attached to the strap. It’s in a mint condition apart from some very minor marks because of storage.
The movement is an ETA 1080 and it ran irregularly with a low amplitude. Most of the time this is caused by a sticky hairspring. The ETA 1080 (17 jewels ) has a fixed stud, with Incabloc and capstones on the escape wheel bearing jewels. I’d estimate this Felca watch to be from the 50s.
