A control device () for controlling power supply to a continuous-rotation motor, of the horological, DC type, is arranged to generate electrical pulses with a lower supply voltage to drive the rotor. The number of pulses per time interval is a function of the load applied to the motor. A voltage divider is arranged to supply the lower supply voltage with a plurality of different values and thus the electrical pulses with a variable voltage. A logic circuit counts the numbers of electrical pulses in successive time periods; to periodically select a voltage value, from among a plurality of different values, as a function of a counted number of electrical pulses or of a succession of counted numbers of electrical pulses; and to control the voltage divider so that the latter supplies the lower supply voltage with the selected voltage value after the selection of this voltage value.
