Abstract
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.

A winding device for an automatic watch with mobile oscillating mass, including comprising:
- at least one watch holder arranged to carry at least one automatic watch;
- and
- motorisation means for driving said at least one watch holder, wherein
- said device includes a multimeter which is arranged to measure a variation in a resistive torque based on a change of a winding angle which is opposed to said motorisation means by a mobile equipment consisting of,
- all said watch holders driven by said motorisation means, and
- all the watches that all said watch holders driven by said motorisation means carry, depending on a degree of winding of said watches,
- said multimeter includes
- speed measuring means to determine a speed and/or a variation in the speed of said motorisation means,
- torque measuring means to determine a value of a torque and/or a variation in the torque at least at one said watch holder, and/or
- a current meter to determine a value of a current and/or a variation in the current of at least at one electric motor that said motorisation means include.
