The chronograph function on my husband's Timex Ironman Triathlon 30 lap watch disappeared the last time he reset the clock time. How can he find it again?

SOURCE: How do tou reset the

Yeah...it took me awhile to figure this one out too.

You can't actually reset the Review function back to zero. Instead, you replace the data with your latest workout.

Here are the steps:
1) turn on heart rate monitor
2) setup HRM zone
3) start chronograph
4) do your workout
5) stop chronograph
6) review your results

Starting the chronograph is the key. This is the step I missed

SOURCE: how do you set Timex Triathlon Ironman watch?

First look for the set button then press it ,a long press and If it is blinking that's the time you to select the hour ,the minutes,the day/date,the alarms and the special features of your watch.The right button the up and down or for scrolling.Try all of this so your time will set.

Hope it may help you;

I had this problem. I simply flipped the metal plate on the back 180 degrees.

I noticed on the inside of the metal plate a pad about the size of the battery, and guessed from the other notes that this must perform some kind of insulating function. Furthermore, the writing on the outside of the metal plate was not oriented "up"... that is if I was holding the watch in front of me like I was reading it, the writing on the back plate was upside down. Both of these clues led me to believe that the plate had been re-installed wrong. Flipping it around fixed (restored) the beep.
