The driving force behind the idea to introduce hydro mechanical technology is simple: Two flexible reservoirs with a capillary attached at each end. In one, an aqueous liquid containing fluorescein. In the other, a viscous transparent liquid. Keeping them apart is the repulsion force of the molecules in each fluid.
At 6 o'clock, two bellows - made from an incredibly strong and supple electro-deposited alloy - are moved by a piston. When the first is compressed, the other is extended, and vice versa, driving the movement of the fluids in the capillary. The meniscus, which marks the separation between the fluids in the tube, displays the time. When it reaches 6 p.m., the fluorescent liquid returns to the original position using a retrograde movement.
