Bifora 934 SI
Description
The Bifora caliber 934 SI is a direct relative of the Caliber 934, with the difference, that it uses a direct driven decentral seconds indication at position “6” and uses only seven rubies.
This movement is probably a more modern one, since it uses a screw-less balance.
The construction is rather simple but well made with a rocking bar winding mechanism below the dial and an inhouse Bishock shock protection system.
