H1 Titanium Bronze
This encounter between fine watchmaking and fluid mechanics is a world first, with two flexible
reservoirs fixed to each end of a capillary. In one, an aqueous liquid filled with flourescine, in the other, a
transparent viscous liquid. When the first reservoir compresses, the other expands, and vice-versa,
causing the liquid in the capillary to move. The fluorescent liquid advances as time passes, and the
breaking point with the transparent fluid - called the meniscus - indicates the exact time. The secret?
Two bellows, each driven by a piston. And this is where the watchmaking mechanism comes in and
activates the system.
