Claim 0:
1. 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.
