Two flexible reservoirs with a capillary attached at each end. In one, a coloured liquid; in the other, a transparent one. Keeping them apart is the repulsion force of the molecules in each fluid. The two reservoirs at 06:00 also referred to as bellows are made of a highly resistant, flexible alloy. Watchmaking is used to activate the system via a piston that drives the bellow on the left (the active bellow). When the active below is compressed, the second expands, and vice versa, resulting in the movement of the liquids in the capillary. As the hours go by, the coloured liquid advances. The meniscus marks the separation point between the two liquids, indicating the hour. At 06:00, the coloured liquid moves backwards, returning to its original position in what is known as a ‘rewind’.
