A model 1883, a nice frosted full plate movement. I found it at an NAWCC mart in clean running condition, it was made in about 1888. I even managed to find a perfect dial and some NOS hands to go with it. My watchmaker didn’t even bitch when I handed him the bits and asked him to make a watch out of it.
typical of American pocketwatches, it all went together well and works perfectly.
I remember when I first went to an NAWCC mart in the mid 1980s, I could buy a running 1883 Waltham for about $20.00 U S. I used them for the parts. Nowadays, a nice “frostie” like @Fritz ’s goes for a respectable dollar. I have three 1883s. Two private labels, one for Joseph Pequegnat of Guelph, Ontario, and one for G W Beall of Lindsay, Ontario. The Beall movement is marked for the Canadian Railway Time Service. The third one is a Canadian Pacific Railway marked movement.
