Abstract

See full text

Method for adjusting the rate of a basic oscillator of a watch arranged to oscillate at a nominal frequency N0, with a master oscillator generating an excitation frequency NE approximately equal to an integer multiple of this nominal frequency N0, the master oscillator subjecting the watch to excitation or a modulated motion during a transition phase after which the basic oscillator is stabilised at the excitation frequency NE, and a state of display correction method with a winder for mechanical or automatic watches, moving a support carrying the watch and comprising a state of display correction oscillator, having a lower variation of rate value than the initial variation of rate value DI of this basic oscillator, and oscillating at a correction frequency NC to impose oscillation or a motion on the watch, during a state of display correction phase whose duration is adjusted to exactly correct a state of display error measured at the initial moment of actuation.
