The short lived Concord C1 Quantum Gravity

The video below shows the HYT H1, which will be launched officially at Basel. Helmed by Vincent Perriard, formerly of Concord and Technomarine, HYT makes “hydro-mechanical watches”. From the video it appears the hours are indicated by the green fluid while the minutes and seconds have hands.

This is not a new idea of course. It first used by Concord in its BNB-made C1 Quantum Gravity watch where it served as the power reserve. I don’t know if the Quantum Gravity ever made it to production.
