Compensator for a mechanical pendulum clock

In combination, a mechanical pendulum clock and a compensator to compensate for disturbance variables that affect the accuracy of the pendulum clock, wherein the compensator comprises an electronic clock generator for generating a reference signal, a pendulum frequency generator for generating a signal representative of the frequency of the pendulum, an electronic controller forming a comparator which is connected on the input side to said electronic clock generator and said pendulum frequency generator to receive said signals therefrom, said comparator producing an output signal, and a motor-driven center of gravity adjusting means for adjusting the center of gravity of said compensator actuated by said electronic controller responsive to said output signal, said compensator being attached to the pendulum.
