There is disclosed an electronic multi-function wristwatch one of whose operating
modes is a memory game which uses the time display means of the watch. In the preferred
version comprising an analogue time display, the watch randomly generates a sequence
of visual indications such as time values and displays it by means of the hands
(3, 4). Then, the player attempts to repeat these indications by entering
a sequence of answers by means of control keys (14-19) arranged facing the
hour symbols (7) of the dial. These keys preferably comprise electrodes
affixed under the watch glass. The watch displays successive sequences each comprising
one or more indications more than the preceding sequence. It can also emit corresponding
sequences of sounds. The watch/user interface can further comprise push-buttons
(11-13) and an alphanumerical LCD display (9).
