Hands? Digital read-outs? All out of date The wristwatch of the future indicates the hour by using miniature pistons and bellows to drive a fluorescent green liquid around a ring.
According to a description quoted by Cory Doctorow at BoingBoing, “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!”
The $45,000 watch was developed by The Hydro Mechanical Horologists, which describes it as “a new dawn in watchmaking.”
