Patent number: 8861315Abstract: A radio-controlled wristwatch that determines whether or not illuminance of light irradiating a solar cell is high, using plural criteria but without directly measuring voltage or current. The wristwatch includes: a solar cell; a control circuit which stops operation under a predetermined condition; and an illuminance detection circuit which indicates illuminance of light irradiating the solar cell being higher than a given threshold value. The wristwatch switches the given threshold value between a first and a second value, larger than the first value, starts the control circuit in a stop state when a signal indicating that the illuminance is higher than the first value is output, receives a satellite signal containing time information from a satellite when a signal indicating that the illuminance is higher than the second value is output, and displays time corresponding to the time information contained in the received satellite signal.Type: GrantFiled: March 13, 2012Date of Patent: October 14, 2014Assignees: Citizen Holdings Co., Ltd., Citizen Watch Co., Ltd.Inventors: Takushi Hagita, Akira Kato
