PUW 2509

Description

This movement was the best and last mens’ size, non quartz-controlled movement, made in Pforzheim. As the former construction with electric contacts was not free from trouble, this movement not only worked without them, but also got an integrated circuit, which was responsible for the correct polarization of the moving coil.
