Beschreibung
Zusammenfassung:	An electronic watch includes a navigation processor that perform navigation processing of causing a positioning processor to perform positioning processing, and calculating a distance to a destination based on current position information acquired by the positioning processing and destination position information, and also calculating a direction of the destination based on current position information, geomagnetism, and destination position information, and moreover causing a display unit to display the direction of the destination, and an operation device configured to case the navigation processor to start navigation processing when a predetermined operation is performed. The navigation processor performs, when the distance is longer than a preset threshold, the navigation processing at a first frequency during a predetermined time after predetermined operation is performed, and performs, when the distance is shorter than or equal to a preset threshold, the navigation processing at a second frequency higher than first frequency during the predetermined time.
