Abstract
Disclosed is a chronograph timepiece in which it is possible to prevent the battery reliability service life time from being exceeded even when the period of time that the chronograph function is used is short, making it possible to prevent failure generation in the chronograph timepiece due to liquid leakage. A 24-hour counter down-counts a period of time that has elapsed starting from 24 hours, and a chronograph counter down-counts the period of time that chronograph measurement operation is performed from a predetermined time; when the count values of the 24-hour counter and the chronograph counter become equal to each other, a processing unit consumes a battery for the residual period of time of the two counters by a battery power consuming unit.
