French watch. The case is smooth and the enamel dial has four separate small dials for duodecimal hours (bottom), decimal hours (top), 31-day date (left), and 30-day date of revolutionary month (right). The dial rim displays the days of the French revolutionary calendar (primidi - duodi - tridi - quartidi - quintidi - sextidi - septidi - octidi - nonodi - décadi) indicated by the long hand. Some revolutionary symbols are depicted in the space between the dials: square and compass, clasped hands, skull, and cap. The movement has a fusee and verge escapement. The decimal hour and Republican calendar were introduced on October 5, 1793, and were abolished on January 1, 1806.
