Abstract (en)
[origin: WO2018172147A1] The invention concerns a method for setting the operating frequency of an electronic watch (10) by means of a computer application installed on a portable electronic device (12), the setting method comprising the following steps, carried out by the computer application: - generating a reference pulsed signal in the portable electronic apparatus - converting the reference pulsed signal into a modulated optical signal composed of light pulses - transmitting, to the electronic watch (10), the optical signal modulated by the light source (35) or by a modulation of the light emitted by the screen (36) of the portable electronic apparatus (12), and the following steps, carried out by the electronic watch (10): - reconstructing the reference pulsed signal from the modulated optical signal received by the optical sensor (16) - correcting an inhibition value stored in a memory (33) of an adjustment circuit (32) of the electronic watch (10) as a function of the reference pulsed signal.
