Bifora 103

Description

Bifora made some very beautiful movements in their history, and this caliber 103 is certainly one of them. With stripe decorations (cannot be seen in this scan), indirect second (which was destroyed by a bad watchmaker) and a very early shock protection this is probably the nicest looking Bifora caliber.

As on many old Bifora movements, it can only be identified on the dial side.
