发明名称 METHOD BY WHICH A TIMEPIECE MOVEMENT INTENDED TO OPERATE AT AMBIENT ATMOSPHERIC PRESSURE IS ADAPTED FOR OPERATION IN A LOW-PRESSURE ATMOSPHERE
摘要 The method for adapting a timepiece movement provided to operate at ambient atmospheric pressure so as to operate in a low-pressure atmosphere comprises the following steps: 1. measuring the quality factor of the movement at atmospheric pressure, 2. measuring the quality factor of the movement at a predetermined low pressure corresponding to the operating pressure intended for the modified movement, 3. calculating the energy gain between the two measurements, 4. adapting the dimensions of the movement based on this energy gain, in particular by modifying at least one of the following elements of the movement: the reduction ratio of the finishing going train, the torque of the barrel, the size of the barrel and the inertia of the balance.
