Brac 502


The Brac 502 is a rather modern constructed pin lever movement: It has got indirect driven hands (including the center second hand), a yoke winding mechanism and a large mainspring barrel.

As shock protection system, a “Trishock”-like three-leg system is used; on the dial side, there’s also the same spring of that kind used, but the bearing is just a metal bearing instead of a synthetic ruby.
