Employee made watches different from standard production well known at Waltham. Here shown is one that is rather special perhaps made to be a special award to internally engraved CHRISTIAN F. HALLER or HATTER. Serial number is listed for model 1883 15j Appleton Tracy 1885, but movement strangely marked Abe Lincoln. The original case is a 4 oz. silver from Blauer with double hidden hinge hand engraved all around. Dial is Waltham made and marked. It is a conventional solar time 24 hour watch not like the Waltham siderial 24 hour star time model 92. Probably unique and special collectible from Waltham and I would like to know by who, how and why it was made.
