This was my grandfather's watch. It's been stored since his death in 1959. I do not have the original band, I was told he was wearing it when he died from a long fall so the band may have been damaged then. I could not find a date code inside, but was told he purchased it in the early to mid 1930s. I just put 1931 in the box above since it required a date to complete page. I have had it repaired and back to operating condition, just always curious of exact year of manufacture and model.
