See full text

An electronic timepiece has a reception unit that executes a search process to search for satellite signals that can be captured from among satellite signals transmitted from a plurality of positioning information satellites, and from among the satellite signals captured by the search process receives a satellite signal with signal strength greater than or equal to a specific signal reception threshold value; an information acquisition unit that acquires specific information including at least time information based on a satellite signal received by the reception unit; and a display that displays acquired information. A threshold value changing unit lowers the signal reception threshold value according to a search count, which is the number of times the search process has been applied to the satellite signals of all positioning information satellites.
