Bifora 91

Description

The midsize Bifora cal. 91 was used a lot in the 60ies and 70ies. It was available in two versions, one with fully integrated, indirectly driven center second and the other with a decentral small sub second. Both versions use the same plates.

Like many Bifora movements, this one uses a Bi-shock shock protection system. It can only be found in Bifora movements.

On the dial side, there's a yoke winding system.
