Constant force mechanism (remontoir)

A constant-force mechanism (remontoir d'égalité) ensures that the movement is always supplied with consistent energy, regardless of the tension of the spring. This ensures stable accuracy throughout its entire service life. This extremely sophisticated Complication It transfers energy portions to the escapement system at regular intervals, often with a visible effect on the dial (e.g., jumping seconds). It is a sign of the highest horological precision.
