ABSTRACT:
A case member is coupled to a plate member so as to be movable between an opening position and a closing position with respect to the plate member. A switch input section is mounted on the upper surface of the plate member. An analog display unit for displaying time with hands is arranged on the upper surface of the case member. An electrooptic data display unit for displaying data is arranged on the lower surface of the case member. An electronic circuit for driving the analog display unit and the electrooptic data display unit is housed in the case member. The switch input section on the plate member is electrically connected to the electronic circuit of the case member. Data input from the switch input section to the electronic circuit is processed thereby and is displayed on the electrooptic data display unit. When the case member is set at the closing position, only the analog display unit is exposed. When the case member is set at the opening position, the electrooptic data display unit and the switch input section are exposed, and functions other than a watch function can be executed.
