Sautoir

A sautoir (French “Sautoir de compteur minutes”) or “jumper spring” allows a hand to advance instantaneously.

Typically found on classic chronograph movements, a sautoir allows the chronograph minutes or chronograph hours hand to advance instantaneously rather than advancing with the chronograph seconds hand.
