Abstract (en)
[origin: WO2013084040A1] The invention relates to a method for adjusting the chronometry of a mechanical timepiece movement intended to operate in a low-pressure atmosphere, comprising the following successive operations: 1. placing the movement in an atmosphere at the low-pressure pre-established for the normal operation of the movement; 2. measuring the advance or delay (typically advance +DeltaRho) of the timekeeping precision of the movement at said low pressure. 3. returning the movement to ambient atmospheric pressure; 4. adjusting the movement in order to compensate for the advance or delay previously measured (typically implementing a delay -DeltaRho) during operation at low pressure; 5. returning the movement to the atmosphere at the low pressure pre-established for the normal operation of the movement.
