Abstract
A method for adjusting the operating frequency of an electronic watch via a computer application installed in a portable electronic device, the adjustment method including the following steps, performed by the computer application: generating a pulsed reference signal in the portable electronic device, converting the pulsed reference signal into a modulated optical signal consisting of light pulses, transmitting the modulated optical signal to the electronic watch via the light source or via a modulation of the light emitted by the screen of the portable electronic device, and the following steps, performed by the electronic watch: reconstituting the pulsed reference signal from the modulated optical signal received by the optical sensor, correcting an inhibition value stored in the memory of an adjustment circuit of the electronic watch as a function of the pulsed reference signal.
