Hamilton 16s Dial Feet Location

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.
