METHOD FOR TESTING THE WATER RESISTANCE OF A TIMEPIECE

摘要

Method for testing the water resistance of at least one timepiece, wherein it comprises the following stages:;E1—Measuring the rate of the timepiece when subjected to a first external pressure, in particular atmospheric pressure, in order to obtain a first reference rate value;;E2—Measuring the rate of a timepiece when subjected to a second external pressure inside a pressurization chamber, in order to obtain a second rate value under pressure;;E3—Comparing the rate value under pressure and the reference rate value in order to deduce therefrom the presence or otherwise of a deficiency in the water resistance in the event of a variation in excess of a predefined threshold.

1. A method for testing the water resistance of at least one timepiece, wherein the method comprises:
measuring a first rate of the timepiece when subjected to a first external pressure, in order to obtain a first reference rate value; measuring a second rate of the timepiece when subjected to a second external pressure inside a pressurization chamber, in order to obtain a second rate value under pressure; at least one of the two operations of measuring the rate of the timepiece includes measuring a time-related difference between two display values for the timepiece provided by two status reports for the timepiece, compared with a time between said two status reports measured by a reference clock; and comparing the rate value under pressure and the reference rate value in order to deduce therefrom the presence or otherwise of a deficiency in the water resistance in the event of a variation in excess of a predefined threshold.
