I bought the sensor but the watch doesn't recognize it. Better to contact Timex before you buy new strap. Just check The reference before. Not all watches match with sensors

I own the T5K672 and it is Analog and worked fine with my chest strap. Make sure that you match analog product with analog reader (as opposed to digital). I also called timex customer service (I googled it), to make sure I had the correct product.

If your original heart rate monitor is a M640, you will need the T5K724 model instead of this one. Your watch detects a digital signal, and this heart rate monitor is an analog instead.

If not installed right, the clip holding battery inplace will loose connection. Ours lasted about 24 days when the watch failed and we returned it. The battery still functioned but the watch didn't.

I have had the same experience in the past with timex watches. By looking at the watch, looking it seems pop out the two pins and you should be good to go. A paper clip should do the job

yes, I just replaced the strap battery, you realize when it need to be replaced because no data is sent to the watch

Yes it comes with the chest strap monitor. I have also found that, by accident, that monitor operates on the same transmission frequency, to the wrist display unit, that is used by Life Fitness treadmills. I get automatic heart rate display from our treadmill.

My unit diea after about a year. I contacted Timex and they replaced it. Only think I can suggest is to contact Timex. Did you clean out the battery compartment to make sure there is not corrosion on the contacts. This is about all I can suggest to you. good luck. PS. Dont be insulted but do you use a good electro gel.Sam S

I belive it is not, although I'm not sure. I bought the strap and it was not compatible with my wrist watch. I think you must first check that out with Timex directly.

i have it over 5yrs still works. i had to replace the watch battery. PITA to replace the watch battery but the voltage was too low and not reading the HR. the watch and the strap are 2 different batteries.(2025 & 2032) easy batteries to find at local pharm chain store. i replaced both at the same time and all good.

The battery in the chest strap you can replace yourself. The battery in the watch it is suggested that you take it to a jeweler to get the battery replaced.

take watch with you to match. Check Walmart, they will put in on. Also check local jewelry stores. They have replaced most of my timex watch bands and also install batteries in a way that keeps the watch waterproof. If all else fails, sent it back to timex to be fixed. Katie

I've had some difficulty getting data from the chest strap to the watch. Not sure if I'm putting the strap in a slightly different position so it can't get a good reading. The watch works PERFECTLY though and I've just been using that. Wish the chest strap worked as well.

Your watch may need a new battery or it is dying. My first watch acted similarly. I just bought another one just like it because I like the heart monitor feature.
