Dynamograph

Indicates the amount of tension in the mainspring so as to maintain it within ideal limits. Developed for watches by Audemars Piguet, it indicates the torque supplied by the mainspring. As long as the Dynamograph hand remains in the delimited zone, the mainspring supplies the movement with exactly the amount of energy for optimal precision. As soon as it leaves this zone, the movement should be wound.
