A winding device includes a motor for driving a watch holder carrying at least one automatic watch with a mobile oscillating mass, and a multimeter for measuring a variation in a resistive torque opposed to the motor by the watch holder equipped with watches, depending on a degree of winding of the watches. The multimeter includes a speed meter to determine a speed and/or a variation in the speed of the motor, a torque meter to determine a value of a torque and/or a variation in the torque at the watch holder, and/or a current meter to determine a value of a current and/or a variation in the current of an electric motor.
