Osco 52

Description

This rather small and old movement from the manufactury of Otto Schlund in Pforzheim is already equipped with a direct driven center second hand and a shock protection system. Nice to see is the screw balance and the long regulator for the hairspring. Not so nice is the simple rocking bar mechanism.
