Method for changing the oscillatory frequency of a timepiece movement

摘要

The method involves allowing an escape mechanism to define a first pitch center (d3) formed by a distance between center of rotation of an escape wheel (11) and center of rotation of a pallet assembly (12). The mechanism is allowed to define a second pitch center (d4) formed by a distance between center of rotation of the pallet assembly and center of rotation of an adjusting element, where the first and second pitch centers are equal to third and fourth pitch centers defined by another escape mechanism.
