Abstract (en)

Constant force device for precise working regulation of mechanical clocks by means of a balanced force transfer from the anchor wheel to the clock regulation organ. Said constant force device is integrated in the tourbillon mechanism. The constant force device works by balancing the decreasing force available from the drive spring (10). As a result a constant torque is applied to the clock regulation organ.
