Abstract

PURPOSE:To prolong the life of a supply battery by limiting the lighting of the light emitting lamps provided to the hour hand and minute hand only to the nighttime by the cam provided to a wheel which makes 1 turn in 24 hours. CONSTITUTION:A plate 3 which is supplied with power source by making sliding contact to a pair of contact springs 2 respectively is provided to an hour hand wheel 1 and the plate 3 and the light emitting lamps 9 provided to the hour hand 7 and minute hand 8 are electrically connected via a pair of contact parts 6 provided to the outside peripheral surface of the hour hand stem 4 and minute hand stem 5. If this watch is a 24-hour watch, a cam 12 is provided to the hour hand wheel 1 as the wheel 10 which makes 1 turn in 24 hours and when the cam 12 enters the lower side of the contact spring 2 as the hour hand wheel 1 rotates, it forces up this contact spring 2, thus separating the contact spring 2 and plate 3.
