HYT story

The Hydro Mechanical Horologists

have turned utopia into reality – mixing mechanics and liquid within a wristwatch. While truly addicted to nonconformism, they have drawn upon the strictest codes in Fine Watchmaking – and felt entirely free to shatter them! By achieving the incredible challenge of indicating the time with fluids, they have not so much propelled a new UFO into the watchmaking stratosphere, as they have in fact pulverized all certainties by uniting two worlds that are supposedly diametrically opposed.
Never since the water clocks of the pharaohs, have the laws of gravity been overcome to transpose this energy in a portable watch. HYT has done it. H1 and H2 represent a new way of timekeeping that marries high watchmaking and science, with cuttingedge design bringing them together.

HYT created watches to experience the fluidity of time. With the liquid time, welcome to the watchmaking 4.0 !

HYT story

The principle?

Two flexible reservoirs with a capillary attached at each end. In one, a coloured liquid; in the other, a transparent one. Keeping them apart is the repulsion force of the molecules in each fluid. The two reservoirs at 06:00 also referred to as bellows are made of a highly resistant, flexible alloy. Watchmaking is used to activate the system via a piston that drives the bellow on the left (the active bellow). When the active below is compressed, the second expands, and vice versa, resulting in the movement of the liquids in the capillary. As the hours go by, the coloured liquid advances. The meniscus marks the separation point between the two liquids, indicating the hour. At 18:00, the coloured liquid moves backwards, returning to its original position in what is known as a ‘retrograde’.

The first hybrid mechanical fluid watch emerges.

The horologist revolution

We knew about clepsydras or water clocks. The oldest found thus far dates back to the age of the pharaohs. It took 3400 years to overcome the force of gravity and indicate the time with a liquid in a mechanical wristwatch. Many have dreamt of it

- HYT has done it -
