Christophe Claret presents his Kantharos, a monopusher chronograph with striking mechanism and constant force, with a fully integrated, self-winding mechanism… yet another on the watchmaker’s list of world-firsts. Many sports use sound to signal the start of a competition. The Kantharos strikes its cathedral gong each time the chronograph starts and stops timing.
