PUW 561 / Dugena 2509

Description

The PUW caliber 561 was the base movement of the last but one movement series of the Pforzheimer Uhrenwerke. The movement plates show, that it was prepared to carry a selfwindig mechanism, better known as PUW 1561.

With 17 jewels, a swiss pallet escapement, an incabloc shock protection and 21600 beats per hour, it matched the standards of the early 70ies movements.

Another, maybe cheaper version, also called “Dugena 2509”, of the 561 was equipped with the uncommon Ruby-Neutro-Shock shock protection system.
