Condition
For parts or repair. The mainspring appears to hold tension, and the train wheels with the escape wheel are present. However, the balance staff is broken (balance wheel does not pivot correctly). The winding stem locking screw is missing. The movement shows age-related patina, minor dirt, and dust. Requires professional cleaning and a balance staff/assembly replacement to run. Sold as-is.
