I use my chronograph often and the battery life seems to last less than one year. What should I do?
Using the chronograph function often or leaving it running constantly will shorten battery life considerably. It is important to understand that more battery power will be required to enable all of the functions other than basic timekeeping. In fact, if left running for extended periods of time, electronic chronograph/stopwatch functions on some watches will stop running automatically. To conserve battery power, it is best to stop the chronograph function when the need for timing is completed.
