The Pocket Watch Database has compiled data covering the major American pocket watch manufacturers and created an easy way to find information using the serial number on the watch movement. Here are a few tips to find information about your pocket watch:
Originally, all Hamilton 16-Size movements were fitted with dials that featured four feet. Starting in 1911, new movements were transitioned to three-foot dials while remaining inventory retained the four-foot dials.
With close inspection, the dial type can be easily identified by evaluating an image of the movement. Due to the differentiation between the foot locations, the four-foot dial is evident when the 21.8 foot hole is prominently visible between the barrel and train bridge. In contrast, the 22.3 foot hole for the three-foot dial is mostly hidden behind the train bridge.
The dial feet on the 4-Foot dial are located at 7.6, 21.8, 38.0, and 50.5.
The dial feet on the 3-Foot dial are located at 22.3, 38.0, and 57.1.
