Question about Timex Sports Ironman Triathlon 100-Lap 66801 Wristwatch
I need to replace the battery in my Timex Ironman Triathlon watch (CR 2025). I don't have my owners manual and didn't want to potentially break something. Do I just unscrew the 4 screws on the back or is there a different way to get access to the battery? Thanks for your help in advance
The Timex Ironman manual and website says to take the watch to a repair facility. Nope! Do it yourself!
How to replace the battery in a Timex Ironman watch:
This is easier if you remove one of the rubbery wrist bands.
1. Take note of the position of the metal back cover. You'll need to reinstall it exactly as you see it in order to hear the alarm.
2. Remove the four screws that hold the metal back cover, and pry off the cover.
3. There is a round metal clip that holds the battery in place, covered with a transparent plastic cover which likely says, "Unlatch to remove battery". Within the center of each clip, there's a small opening just large enough for a straight pin to be inserted. A jewelers screwdrive won't work - use a straight pin. Insert a straight pin into the tiny opening at the edge of the clip, and wiggle it. The clip should release. You'll only need to unlatch one side of the battery retaining ring.
4. Gently pry up the batter retaining clip, then pry up the battery. Insert new battery.
5. Replace the clip.
6. Insert a flat blade screwdriver into a slot which has two "electrodes" or pins - they need to be shorted with the screwdriver to reset the watch. Just touch the screwdriver blade across the two pins to short it.
7. Reinstall the back cover but be sure to position the cover so the alarm sounding place ( a small disc attached to the inside back cover) will reside over the sounding spring.
8. Insert screws.

Getting one side of the the flexible rubber watchband loose wasn't easy, but eventually it came off in the traditional manner (compressing the pin from either end). While working, take care not to cause either of two springs to fall out. I found instructions on the battery cover which said, "After battery insertion, short AC to battery +." How to do that wasn't explained. I found neither hole nor prongs to short, so I simply shorted the battery to the metal nearby using a metal screwdriver. I can't say for sure it worked, but the watch did reset after a few seconds of waiting and worrying that I had ruined the watch. It started working just fine. In addition to the normal modes, there is now an additional one called DEMO. Everything else seems normal again.

While following DaveN4EF's excellent directions, I got stuck with the reset. What ever I did, it would not reset.... I took the battery out, put it in again and it worked like new.
Thanks, Dave for the great directions

Insert a pin into the one end of the metal latch and presto in unhooks! I just figured it out.

Just take it to a local jewelery store and they will change it for you for about $10 to $12. Joe
