Notes This is one of the Potter's earliest watches made on Swiss soil according to his design developed and patented in America. There are minute differences between the early and later Potter chronometers; early ones have spotted movements, the later ones are usually decorated with Geneva stripes and were almost always stamped with Potter's large trademark, whereas the early ones were not. According to Kalish, Potter used to say, that he did not have to stamp his cases, because everyone knew his workThe stem in the early ones is hold by a screw mounted in the center of the pendant sleeve; in the later, it is flush with the body of the case. The early ones have atraditional balance spring stud, the later ones are more elegant.See also note to the following lot. "
