    (54) Electronic timepiece with analog time display unit and electrooptic data display unit


    (57) An electronic watch includes a plate member (2) having an upper surface on which a switch input section (6) is mounted, and a case member (1) arranged on the plate so as to be freely opened and closed. An analog display unit (4) for display time with hands (13) and an electrooptic data display unit (17) for displaying data are respectively housed in the case at its upper and lower surfaces. An electronic circuit (28) for driving the unit (4) and the unit (17) is housed in the case. The section on the plate is electrically connected to the circuit so that data input from the section can be displayed on the unit (17). When the case is closed, only the unit (4) is exposed. When rhe case is opened, the unit and the section are exposed, and functions other than a watch function can be executed.
