I only have a few Walthams. This is a Grade 18 from 1902. Size 18, 7 jewel, no adjustments. A Keystone silveroid case that's "guaranteed" but not for a specific period of time.
Runs but is missing its hands. I'll have to see if I can get hands for it. It's too nice a watch to use as a parts donor.
Acquired: 2019
Circa: 1902
Current condition: runs but missing hands.
