Notes

The elegant plate design of this caliber, patented on April 5, 1887, allows for easy setting of the train. The winding/setting mechanism, although not patented, is unique for Potter: its intermediate setting wheel moves vertically for engagement, the click pin protruding by the barrel affords an easy and secure means of letting the spring off, and the glazed cuvette, typical for Potter, allows the movement to be viewed.
