A 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 device of the watch, and, following activation of the winding mechanism, await the determination of the stabilisation of the nominal running of the resonator by these monitors before allowing adjustment of the state of the watch.

A device (1000) for the winding and time-setting of a watch (1) with an oscillating resonator (2), which includes: an automatic winding mechanism (304) for a mechanical or automatic watch, which includes at least one watch reception support (305), a viewing system (1002), a stoppage monitor (500) to observe the stoppage of a resonator (2), and a controller (900) arranged to identify the stoppage time displayed by the watch (1) in the stoppage position thereof, to compute the time remaining until a synchronization between the actual time indicated by the clock (1001) and the stoppage time, and, when the remaining time has elapsed, to activate the automatic winding mechanism (304) for rewinding the power storage device of the watch (1).

Universal device (1000) for the winding and time-setting of a watch (1) with oscillating resonator (2), which comprises:

rewinding and state correction means, comprising an automatic winding mechanism (304) for a mechanical or automatic watch, which comprises at least one watch reception support (305),

state measurement means (303) relative to a reference clock (1001), comprising a viewing system (1002),

stoppage monitoring means (500) to observe the stoppage of a resonator (2), and control means (900) arranged to then identify the stoppage time displayed by said watch (1) in the stoppage position thereof, to compute the time remaining until a synchronisation between the actual time indicated by said clock (1001) and said stoppage time, and, when said remaining time has elapsed, to activate said automatic winding mechanism (304) for rewinding the power storage means of said watch (1).

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.

A barrel for a timepiece. The barrel has a device for limiting the number of running rotations of the barrel, wherein this device still allows any number of winding rotations of the barrel.
