Brac 37


Brac 37Brac 37


The Brac caliber 37 is a classy, jewel-less pin-lever movement.
Surprisingly, it is equipped with a yoke winding mechanism, which is unusual for movements of this low class.

Nevertheless, many things of the construction are still the same, as on Roskopf watches, e.g. the large click spring and the indirectly driven hands as well as the low beating rate, which is below 5 A/s.
