An encounter between Fine Watchmaking and fluid mechanics. One might say a utopia. Shattering all certainties, steamrollering conformity, the idea that led to the H1 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 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. The two reservoirs at 06:00. While the first compresses, the second expands, and the other way round, resulting in the movement of  the liquid in the capillary. A MECHANICAL MOVEMENTTO ACTIVATE THE HYDRO SYSTEM Orchestrated by Brino Moutarlier, alongside Jean-François Mojon and his Chronode SA team, a mechanical movement is situated in the upper part of the watch, and propels a cam
