CA 2421470

In an electronic timepiece having a power saving mode, to prevent a situation in which a long period of time is needed for confirming a measured time period from being brought about. A mode control portion outputs a power saving processing signal to a display driving portion when an operating portion is not being operated for a predetermined time period in a state in which a chronograph measuring portion is not operated to measure a time period and a display driving portion erases display of a display portion to constitute a power saving mode. When the chronograph measuring portion carries out time measuring operation, the mode control portion prohibits the operation from being shifted to the power saving mode even when a nonoperational time period of the operating portion has elapsed the predetermined time period and therefore, a measured time period measured by the chronograph measuring portion is displayed at the display portion.
