Abstract: A method for adjusting a timepiece including: providing a portable object including a screen and a camera; testing accuracy of a piece of time information of the timepiece by using the camera of the portable object to compare with a piece of time information obtained from an external source; sending the time information from the portable object to the timepiece if a difference is detected, the timepiece including at least one phototransistor arranged at a case for receiving the time information, the timepiece to display the correct time information, the sending including: defining on the screen of the portable object an area of shape and dimensions similar to the case of the timepiece; holding the case of the timepiece against the area; sequentially displaying black or white in the area, in a sequence of black and white corresponding to a luminous coding of the time information.

Abstract: An electronic module including at least one electric motor for driving an analog display, a clock module including a time base delivering a clock signal connected to a divider circuit, the divider circuit delivering a reference signal sent to a control circuit arranged to control the electric motor, the clock module further including a measuring and correction circuit arranged between the time base and the divider circuit and delivering an intermediate compensated signal. The time base, the compensation module, the divider circuit, and the control circuit are arranged in a same case to form the clock module.

Abstract: The invention concerns a synchronisation method between analogue display means (4, 6) and a volatile time counter (8) in a multi-function electronic watch when the primary powering means (18) powering said watch are replaced, including the following steps, (i) calculating a value (Vtps) representative of a time information item by means of the time base (14) of the watch; (ii) storing the value in the volatile time counter; (iii) updating the value in the volatile time counter periodically as a function of the supply frequency of a time information item by the time base; (iv) synchronised display of the value representative of a time information item by the analogue display means in a first operating mode of the watch; (v) non-synchronised display of a value not representative of a time information item by the analogue display means in a second operating mode of the watch; (vi) detecting the end of life of the primary power means powering the watch; (vii) setting the analogue display means in a predetermined

Abstract: The present invention concerns a method for detecting the start of a dive for implementation in a portable electronic device (1) of the diving computer type. More specifically, the method is for implementation in a device of this type having at least a first operating mode and a second operating mode, called the dive mode. This device includes a pressure sensor (5) for measuring the ambient pressure value (P) and electronic circuits (2) for processing the pressure measurement results including a time base (4) and at least one memory zone (7, 8). The detection method according to the present invention more particularly proposes making correction to certain measured pressure values before storing them as reference pressure values (Pref). Thus, the start of a dive can be detected with a high level of reliability solely on the basis of ambient pressure measurements.
