A method and device for determining a constant parameter of an inhibition value for adjusting the device operating frequency of a watch equipped with a quartz oscillator. The following steps are performed by a self-calibration circuit of the electronic watch device: from a first external pulse and a second external pulse received from a system external to the watch and separated by a measurement time, corresponding to a reference number of reference periods for a periodic calibration signal derived from the time-measurement signal and having a calibration frequency derived from the natural frequency of the quartz oscillator, determining a calibration parameter representative of a ratio between a calibration period and a reference period for the periodic calibration signal, and determining a constant inhibition parameter as a function of the calibration parameter.

The method for test the rate of an electronic watch with a time base device (1) comprises three main steps for the test on test equipment. The time base device comprises at least one watch module (2) with a resonator (3) connected to an oscillator of an electronic circuit (4), which is followed by a divider circuit, which is controlled by an inhibition circuit, and which provides a divided timing signal for a motor.
