Breguet Breguet and its President & CEO Marc A. Hayek are renewing their support to Only Watch by participating in the 6th edition of the biennial charity auction co-organised by the Monaco Association against Muscular Dystrophy and the Monaco Yacht Show. Within this context, the Maison has developed a one-of-a-kind creation for this sale, from which the proceeds will benefit research on Duchenne muscular dystrophy: a special Type XXI chronograph, made for the first time in platinum.
