Watchismo gives us an early look at Vincent Perriard & Co's HYT H1, a concept watch starting at $45,000 that will debut at the Baselworld 2012 show. It uses liquid-driven pistons as well as gears to tell the time. I am agog.
Pistons in the movement move the bellows. As one expands the other one compresses which moves the green Fluorescein liquid. Fluorescein even has applications in forensics to detect latent blood stains but this is likely a first and only use in horology!
