Here is my Hamilton 942, private label to A. Wagner & Bro. Monroe, Michigan. As can be seen both dial and movement are signed.
The 942 was the highest quality Hamilton ever made for a 18 size 21 jewel watch, together with its grade 943 hunter case sister. It received higher finishing than the far more common railroad workhorse, the 21j 18s grade 940. A period advertisement from 1903 can be seen here.
This particular watch was finished by Hamilton May 25 1901, and sold June 14 1901 to A. Wagner & Bro. Monroe, Michigan. Grade 942 was first made in 1898 and production stopped in 1914. However, as this was an expensive watch, the last movements of grade 942 were not sold until 1919. A total of 5913 movements were made.
