Hublot’s avant-garde watchmaking and the world of motor sport were made for each other. Two leading-edge technologies, in search of new materials, in total fusion with their goal. Similar materials, explored down to the last detail in their quest for the ultimate performance. This meeting of minds has today been crystallised in the form of two partnerships announced at Monaco on 25 and 26 April.
