[Scope of Claim for Utility Model Registration] In a lighting circuit for a watch, comprising: a sensor circuit that outputs a detection signal when a human body is detected; and a lighting circuit that illuminates for a certain period of time in response to the generation of the detection signal from the sensor circuit. , the sensor circuit detects that a human body is within a certain area and outputs a detection signal, and further responds to the detection signal from the sensor circuit when the human body remains within the certain area for a certain period of time or more. a first timer circuit that outputs a drive signal for driving the lighting circuit; and a first timer circuit that counts the number of times a detection signal is generated from the sensor circuit, and drives the lighting circuit when the count value reaches a constant value. It is characterized by adding a counter circuit that outputs a drive signal, and a second timer circuit that resets the counter circuit when the detection signal is not generated again within a certain period of time after the detection signal is generated from the sensor circuit. clock lighting circuit.
