Förster 152


The Föster caliber 152 is a 10 1/2 ligne handwinding movement from the german manufactury Förster, which was located in Pforzheim.

The construction of this movement is very classic, with a balance with two legs and a direct driven center second. But there are also a few notable anomalies, such as the Incabloc shock protection, the extensive usage of deck jewels and the winding pinion with its conical dents (look at the dial side!).
