waltham serial number 18450731 which show to be 1883 7 jewels. This watch is key wind and key set. Dennison case sterling hunter 223950.

Is this watch a Franckin watch or did waltham produce such a creature? I can find no information on such a movement.

To answer my own question. This is a waltham produced for the english market, waltham did produce key wind key set model 1883 off and on till 1919 for export to england and used dennison cases. So as far as I can tell 1912 would be appropriate.
