An encounter between Fine Watchmaking and fluid mechanics. One might say this Swiss luxury watch is a utopia. Shattering all certainties, steamrollering conformity, the idea that led to the H1 Titanium Black DLC watch was simple and consisted of two flexible reservoirs fixed to each end of a capillary. In one was an aqueous liquid filled with fluorescein, and in the other, a transparent viscous liquid. To keep them separate: the repulsive force of the molecules in each liquid, with a meniscus to mark the boundary between the two. As the hours go by, the fluorescent liquid advances.

The meniscus, in the shape of a half moon, marks the breaking point with the other fluid in the tube, indicating the time. At 18:00, the fluorescent liquid of this unique watch comes back to its original position, going backwards. The secret that gets the reservoirs going ? Two bellows made of a highly resistant, flexible electro-deposited alloy, each driven by a piston. And this is where watchmaking comes in to activate the system.
