Abstract In an electronic watch the indication of the time (hours, minutes and possibly seconds) is given in analog form by means of a first passive electro-optic display cell. The display segments of this first display cell are arranged radially with respect to a central point, and the activated segments thereof have the appearance of the conventional hands of an analog watch. The watch comprises a second passive electro-optic display cell furnishing information in digital form, for example indicating the day of the week and the date. So that only the second cell need be provided with an illuminating device, the watch comprises a selector which is manually operable by means of a push-button which, when it is operated, causes the time to be displayed by the second cell at the same time as the illuminating device thereof is operated. This arrangement enables the user to know the time in the dark without it being necessary to provide the first cell with an illuminating device.
An electronic watch comprising: (a) means providing present time-of-day information and also other information; (b) first passive electro-optic display means for displaying in analog form said present time-of-day information; (c) second passive electro-optic display means for continuously displaying in digital form one of said present time-of-day information and said other information; (d) lamp means for illuminating only said second display means; (e) selector means for applying to said second display means either said present time-of-day information or said other information; (f) manually operable push-button means for concurrently operating said selector means to display said present time-of-day information on said second display means and to activate said lamp means.
