Abstract
An electronic wrist watch having a sound producing unit and an electrooptic data display unit, has a single flat plate member a lower surface of which is contacted with a user's hand, and a case member which is attached to one end of the plate member so as to be freely opened and closed over the plate member. A switch input section for data input is mounted on an upper surface of the plate member. An analog display unit for displaying time with hands, and a sound emitting section are mounted on the upper surface of the case member so as not to overlap each other. An electrooptic data display unit for displaying data is mounted on the lower surface of the case member. A sound producing unit and an electronic circuit for driving the analog display unit and the sound producing unit are housed in the case member. The sound producing unit is located under the sound emitting section in the case member, and the electronic circuit is electrically connected to the switch input section so as to cause the electrooptic data display unit to display data from the switch input section.
