Abstract (en)

The method involves calculating and storing a value (Vtps) representative of time information in a time counter. The value is updated based on a function of a supply frequency of the information, and is displayed using an analog display unit in a time mode. A value non-representative of the information is displayed in a non-time mode. The end of lifetime of the power supply is detected and the unit is set in a preset reference position. The value of the counter is set to a preset reference value and the unit is synchronized with the value of the counter during the replacement of the supply. An independent claim is also included for a multi-function electronic watch.
