Movement Serial No.:
Case Serial No.:
Movement and case dated L9; has the distinctive lugs of a Winchester, but has scalloping on the sides of the case that doesn't match up to any ads or watches in the data base. All shown have smooth sides. Signed 4 times and has a "X" shadow dial with lume at indices and on hands. Mounted on a period generic band. Very little wear and is keeping perfect time. Is this a Winchester variant or something completely different that I missed?
