According to the definition of the Haute Horlogerie Foundation, a regulator is a watch "whose two main hands are not coaxial. The minute hand has always been the largest and had a central position. The regulators are known for their precision simply because the axes of the needles do not collide. The measurement of time is thus faced with less friction. With its so particular dial, one may wonder whether there is a hand missing in this somehow special watch. They are simply gathered on the same axis (the barrel), each has its own dial, its own space-time, in the end, an extremely precise time indication, although unusual: it is the minutes hand that, with its rapid movement, dominates and leads the dial, rousing in its movement hours and seconds, respectively positioned at 13 and 9 o'clock.
