  • the innovation still concerns the use of an automatic watch winder for mechanical or automatic watch, with at least one watch receiving position, or movement, or the like, for subjecting at least one entire watch to an excitation oscillation generated by a master oscillator arranged to generate an excitation oscillation at an excitation frequency which is equal to a nominal frequency N0, or to an integer multiple, in particular odd, of said nominal frequency N0, with a master difference AM of error of to a reference for the adjustment of a watch. More particularly, this reference is an absolute reference as defined above, whose operating error is less than 1 second per day, advantageously less than 0.1 seconds per day, for the adjustment of a watch.
  • This watch comprises at least one usual oscillator arranged to generate an oscillation at this nominal frequency N0, with an initial difference DI of any operating error.
  • This automatic winding comprises excitation means, which are arranged to subject the entire watch to an excitation oscillation generated by the master oscillator, and / or drive means arranged to subject the entire watch to a modulated movement generated. by the master oscillator.
  • This gait adjustment is made by subjecting the entire watch to an excitation oscillation generated by the master oscillator, and / or to a modulated motion generated by this master oscillator, for a time sufficient to stabilize the error of operation. of the oscillator of the watch at a difference in operating error less than or equal to the master difference AM.
  • this gait adjustment and state correction device comprises a state correction oscillator, which is arranged to generate an oscillation at a correction frequency NC for the correction of the state of the watch by the submission of this entire watch. a correction oscillation generated by this state-correction oscillator, and / or a modulated movement generated by this state-correction oscillator, for a time sufficient to effect the required correction of the state of the watch.
  • the gait adjustment and the state correction are not made at the same time. But one and the other can be carried out successively, in a short time, for example during a night, or during a period when the user does not need to use his watch.
  • the innovation is applied to the running adjustment of an electronic watch, with, of course, a master oscillator operating error substantially lower than that of the usual electronic watches.
