Abstract
When an inclination switch SW3 is turned on by inclining a wristwatch 12 up at 12 o'clock within a predetermined time after an acceleration switch SW2 is turned on in a state where an auto mode on/off subswitch SW1-1 is on, a lighting circuit lights up an electroluminescence panel EL and puts off same automatically after a predetermined time has passed. If the auto mode subswitch SW1-1 is off, there is no possibility that the panel EL will be lighted up even when the user makes a motion to look at the time displayed on the wristwatch. As a result, the panel EL is not recklessly lighted up excluding by the user's intended motion, useless power consumption is suppressed to prolong the life of a battery used.
