Method for optimizing an operation of setting and winding a watch, and device for implementation of same

A method for optimising an operation of setting and winding a watch or a timepiece movement thereof, disposed on a jig or a table with fixed reference of a servo-control device having means for moving the watch or the timepiece movement for implementing the method, for which the method comprises:

• a step of initially making a measurement of an operation of the watch or of a timepiece movement of the watch, followed by an activation of an operation of controlled shaking of the watch or of the timepiece movement on said jig of a servo-control device generating an oscillating signal, or conversely initially implementing an activation of an operation of controlled shaking the watch or the timepiece movement before making a measurement of the operation of the watch or of the timepiece movement;
• and
• a step of resuming the controlled shaking in phase with the oscillating signal or a synchronisation step for synchronizing with respect to a reference oscillator of the watch, being implemented at an end of the first two steps,
• wherein the controlled shaking oscillating signal comprises a change in sign of a rotation speed in each successive oscillation period with respect to a fixed reference frame of the table of the servo-control device turning at a mean speed, the oscillating signal comprising, over each oscillation period, a positive part and a negative part of the rotation speed, an amplitude of an absolute value of the positive part of the oscillating signal, being different from an amplitude of an absolute value of the negative part.
