摘要： A compensator for a mechanical pendulum clock has on the rear side of a pendulum bob a center of gravity adjusting device, which is actuated by an electric motor. An electronic controller, which is designed as a comparator and which works as a function of the difference between the signals of a pendulum frequency generator and a clock generator designed as quartz reference oscillator, serves to drive the electric motor.
