In for service is a nice black dial Lord Elgin 23 jewel wrist watch. The Calibre 730 movement features a unique free sprung spiral balance wheel. The movement is regulated by rotating a bar with brass weights.
The movement is uncased, dissembled and cleaned.
Then reassembled, oiled and regulated.
Note: An observant reader pointed out that the crystal that was on this watch is not correct, as it should span the entire bezel.
