Abstract: 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.
