Claim 13:
14. A device for winding and setting the hands of a watch comprising an oscillating resonator arranged to generate an oscillation at a nominal frequency N0, said device being configured to rewind and correct the state of said watch, comprising the watch self-winding device according to claim 13, said device comprising a state-measuring structure configured to measure the state of said watch, relative to a reference clock to which said state-measuring structure refers, which comprise a visioning system comprising at least one camera of said illumination device, and to which is coupled said time base of said illumination device wherein said device is configured to detect the stopping or the running of said oscillating resonator of a watch, and a main controller, with which said first controller of said illumination device is interfaced, and which is arranged so that, when a stop is detected, the main controller identifies, according to information transmitted by said state-measuring structure, the stop time displayed by said watch in the stop position thereof, and calculates the time remaining until synchronisation between the actual time indicated by said reference clock and said stop time, and, upon expiry of said remaining time, the main controller activates said watch self-winding device in order to rewind the energy storage of said watch.
