At the intersection of Fine Watchmaking Street and Fluid Mechanics Avenue, one can find this particular titanium watch. Its hydro system is interlaced with the mechanical movement in a fine, waterproof system. The two flexible reservoirs contain a fluorescent liquid and a transparent viscous liquid; as the fluorescent one advances, it interacts with the other liquid in the tube, thus telling the time.
The principle: the two reservoirs are at 6:00, and as the first one compresses, the other one expands (and vice-versa), allowing the liquid to move in the tube. At 18:00, the fluorescent liquid comes back to its original position, going backwards. The hydro system is activated by a fine mechanical movement.
