ABSTRACT:
An electronic watch comprises two passive electro-optic display devices one of which provides a digital display and the other of which provides an analog display. In one operational mode, the analog display device displays the local time while the digital display device furnishes other information such as the days of the week and the dates, for example. In another operational mode, which is selected by means of a push-button, the analog display device comprises only one activated segment (constituted or formed of a ray) which is consequently visible, to indicate opposite a scale of the time zones which time zone is actually selected, the digital display device then indicating the time of the selected time zone. The selection of the time zone which is displayed by the digital display device is effected by means of another push-button.
