1987, Daniel Roth founded his eponymous brand. After working at Audemars Piguet and creating the current Breguet, he was one of the first master watchmakers to decide to go independent and put his vision and talent into a watch with his name on the dial. This Chrono Monopulsante was launched in the early 1990s and, among its special features, uses a Lemania 2220 Vintage ebauche from the 1930s; only 52 examples of this watch were produced, 36 in yellow gold and 16 in platinum.10 additional movements were later discovered and encased, which can be differentiated from the original models by their swan-neck regulator.
