Restoration Work: Watch had a series of faults due to poor maintenance and strength of mainspring. The top and bottom mainspring barrel arbors were worn. These were tightened. Due to the same problem, the center wheel top pivot was out of center, this was corrected. In addition the watch suffers from a poor canon pinion extraction, which damaged it. It was not replaced but tightened and the watch functions properly.
