To mark the fifth Only Watch charity auction, Christophe Claret presents X-TREM-1 Pinball, a unique timepiece designed to reflect that most precious of children's activities: Play. Taking its inspiration from pinball machines, Pinball is a highly distinctive interpretation of Christophe Claret’s X-TREM-1 with its tiny metal balls indicating hours and minutes through new, grilled sapphire tubes. The Le Locle-based watchmaker has also reworked the appearance of the movement so it resembles the inside of a pinball machine: Bumpers, slingshots and balls are all evoked inside the highly visible mechanism. Even the cool blue and bright orange colours reflect the Pinball concept. The Manufacture is dedicating the X-TREM-1 Pinball to Only Watch 2013, the charity auction to benefit research into Duchenne muscular dystrophy, held in Monaco on September under the patronage of HSH Prince Albert II.
