PUW (Pforzheimer Uhrenwerke) 1075E

The PUW 1075E is a manual-winding movement manufactured by Pforzheimer Uhrenwerke, released in 1955. It measures 12.4 mm in diameter and contains 17 jewels with Incabloc shock protection. The movement features a small seconds display and is distinguished by slotted construction on the train bridge, a characteristic shared with other Girard Perregaux-derived designs of the era. Production appears to have continued into the 1960s, primarily serving dress watch applications.
