Helen Daniel Moilliet (1721-1803), son of Abraham Moilliet, was a master watchmaker and salesman in Geneva. He mainly made watches with enamelled cases which were decorated with pearls, precious and semi-precious gemstones. But he also made technically complicated watches with striking mechanisms and calendars. He also made highly complicated figure automatons.
