Vincent Perriard and crew have apparently gone from overseeing the Concord C1 QuantumGravity watch and its fluorescent liquid battery gauge to designing another high end watch that combines mechanical action and fluid measurement with the HYT H1. This hand-wound timepiece has a 65 hour power reserve and displays the time via pumping bellows that push bright green fluorescine past the time markers. A rendered video embedded after the break does more to explain how the watch works, but may not help you figure out its rumored $45k price tag.
