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.

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.

An electronic time keeping device has a stepping motor including a rotor, a stator and coils mounted in unitary fashion. Hands of the minimum unit of time are mounted directly to the shaft of the stepping motor. Gear mechanisms, electronic parts and the like are accommodated in a depressed portion on the upper surface of the time keeping device.
