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.
