HYT H2 Watch

The new tour de force from the Hydro Mechanical Horologists.
This watch employs liquids, the traditional enemy of horology, using bellows that pump transparent oil and water around. Where the two immiscible liquids meet in a tube tells you the time. Hydro mechanical horology at its most excellent.
