Brac 512

Description

The Brac 512 is a rather modern constructed pin lever movement: It has got indirect driven hands (including the center second hand), a yoke winding mechanism, a large mainspring and on the dial side a date indication with semi-quickset mechanism.

This movement was available in different version, with one and seventeen jewels. A noteable fact of the 17j version is, that on the dial side, a KIF Trior shock protection was used, while the balance cock contained a three-leg shock protection.
