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 device is disclosed for verifying the state of a watch and resetting it to the correct time. In a case of the device, a watch can be disposed on a watch support, which can be moved from a position without measurement to a measurement position in a vision system, or vice versa. In a position without measurement, the watch on its support can be observed from the outside of the case of the device through at least one electronic shutter activated or an optical valve activated to be in a transparent state, whereas in the measurement position, the electronic shutter or the optical valve is deactivated to be made opaque.

A watch winder fully winds the watch main spring of various brands of automatic watches, avoiding wear and tear caused by excessive winding caused by prior art winders. In contrast with prior art watch winders, which wind watch main springs a predetermined number of turns, the inventive watch winder precisely detects a fully winded condition of the watch main spring, and stops winding. Prior art watch winders lack that sensing feature, so they continue winding fully winded watches until the predetermined number of turns has been completed. Additionally, the inventive watch winder eliminates the need to guess the number of turns and direction of rotation for different watches. The inventive subject matter further includes methods, which employ deviations in rotation speed to determine watch main spring winding states, such as under-winded, mid-winded, and fully-winded.
