I am trying to figure out the age and originality of this watch. The movement is private labelled "Scharnke & Will, Pittsburgh PA" but it also says Fogg's patent and a number.
Can I use the standard Waltham serial numbers to date?
The movement appears to be key wound. However the dust cover hole does not line up with the winding movement. Does this indicate a modified movement or a new(er) case for an older movement? There are number markings on the case but no maker listed.
Finally, the crystal seems to be very thick. Again this leads me to believe that the case is a replacement. And I am not sure what happened to the hour hand.
Any insight is appreciated.
