Universal device for the winding and time-setting of a watch with oscillating resonator, including a rewinding and state corrector, including an automatic winding mechanism, state measurer relative to a reference, stoppage monitor to observe the stoppage of the resonator, running monitor of the resonator, controller to identify the stoppage time displayed, compute the time remaining until a synchronisation between the actual time indicated by the reference and the stoppage time, and, when this remaining time has elapsed, activate the winding mechanism to rewind the storage means of the watch, and, following activation of the winding mechanism, await the determination of the stabilisation of the nominal running of the resonato by these monitors before allowing a fine adjustment of the state of the watch.
