Created to break the sound barrier Inspired by watchmaking’s past and the possibility of moving musical timekeeping into the future, Blast Hourstriker wants you to hear time again, not read it. When the striker is on, the mechanical ballet that makes the watch’s sound is visible on the hour and half hour, but even its occasional activation is just as beautiful. The mechanism, driven by a specially dedicated barrel, is triggered, the hour rack and the inertia regulator start to turn; the hammers hit the gong whose shape has been subtly worked to bypass the cage of the flying tourbillon.
