Question about Timex Sports Ironman Triathlon 100-Lap 66801 Wristwatch

Error Code Display

I have had my watch for nearly 4 years.  I replaced the battery once, but now I am getting a code on the watch.  First it displays a number code (814017) at the bottom of the screen and then reset itself to January 1 2000.  What could be the problem?  I have never seen this before and this is my second Ironman watch.  Only had to replace the battery when it went completely dead.  Thanks.

Re: Error Code Display

Mine did the same thing after changing the battery and would reset intermittently without warning. For some unknown reason I decided to open the watch again. This time I reset the time and date with the back off the watch while deprssing the small spring that is there on the inside . Haven't had a problem since. Don't know if this is the solution but it worked for me. Good luck!

Re: Error Code Display

I have the same problem. Timex has made sure the internals of the watches hate having their battery changed. It's just so they can make us think "Why change the battery, just buy a new one." And really, it works. I've given up on mine. Time to move on to a nice Casio. Sorry. Unless you are a really technical expert on watches, you're pretty much SOL.

I have a number of these Casio and Citizen watches. This watch does not use GPS for the time keeping. It uses a land based broadcast time signal. There is public information about where the signals come from for your area. The technical breakdown of the time code signal is public access information.

The instruction manual of the watch has the information about when your watch should automatically receive the time signal, and how to set up the watch. Many of the manuals also included a map showing the time signal coverage, and includes the time of day information to show when the signal is strongest.

Make sure the watch settings are for your time zone. This is important. If the main time zone is not for your area it will be trying to receive the signal at the wrong frequency at the wrong time of day. There are areas where the signal may not be able to be received. You can get the mapping for this from the service that the watch has been set to use.

In North America the auto time receive is supposed to take place between midnight 00:00 to 04:00. In the eastern part of North America the reception is poor compared to central and western part of North America. Check the instruction manual for your watch for details.

Below is the spec listing of your watch.

    I have a Casio 1470 pathfinder watch. I did not use it for several years The batteries ran down, have replaced them and now have no display or functions

    mcdevito75 here, I would see the jeweler who installed the new batteries and ask to have the battery install double checked so they are makeing proper contact with the LCD movement. In the meantime you can try to hold down the MODE button for a few seconds and see if the display appears, also if the display screen has turned very dark, your Casio may have had it, as the LCD display could have gone bad. New batteries should bring up a display even after the watch has been stored. Hopefully the display is still a grayish color and the new batteries need re-alignment.

    Screen is blank. This is a solar watch. Does battery need to be replaced? About 4 days ago it displayed wrong time, year, and date. I manually reset and just this morning that I have no display and am...

    Some watches do have a battery inside for reserve energy if it is an older watch 10 years it may need a new battery...or the one in it is's hard to say when in doubt just replace the battery since it only costs a few dollars.

    Also you can leave it in INDIRECT sunlight for a day and see if that works.

    Random display resets of TIMEX Ironman Triathalon(100 lap memory)

    Hello RLOWE803,

    While I was looking for pictures specific to resetting this watch, I came across your post and thought to reply. I recently replaced the batteries on my watch, which I have owned for nearly 7 years. It is an Ironman Triathlon 100 Lap watch. When I replaced the batteries this time, I forgot to reset, in essence reboot the system, by using a metal needle point tweezers to briefly connect the positive side of the battery to the "AC" pad on the small circuit board for at least 2 seconds. I remembered to do this with at all the other times I had replaced the battery and did not have any troubles after it. This time I forgot and now have the same issue you described. I am not sure where the "AC" pad is on the back of the module. But, it should be apparent if I did it correctly in the past.

    Give that a try before sending it off to be repair and wasting time, money and trouble.

    Good luck,

    Do not panic yet - all you need is the battery replacement.
    Don't mind that the watch is less than a year old - it may laid in sellers store for a year or so and as the watches are not refitted with the brand new battery at the selling point, they may have underpwered battery much more quicker than you expected
    Find your nearest watch repair shop and ask for battery replacement. Your watch will tick as brand new and will last much longer then before.

    Do not forget to rate, please.
