| 摘要 | A method for adjusting the rate of a watch with an oscillator arranged to generate oscillation at a nominal frequency N0, with a servo-system including a master oscillator arranged to generate excitation oscillation at an excitation frequency NE, which is approximately equal to, or equal to the nominal frequency N0, or to an integer multiple of this nominal frequency N0, the watch is subjected to excitation oscillation or to a modulated motion, generated by the master oscillator, during a transition phase after which the oscillator of the watch is stabilised at excitation frequency NE, and there is incorporated in the servo-system a winder for mechanical or automatic watches, arranged to move a support on which such a watch is fixed. | ||||||
