It seems others are having the same issue - save your money - avoid this piece of junk.

I tried to pair same with my TGT first by selecting Scan under speed/cadence (after) installing it on the bike (this did not work).

Only getting cadence output with no speed data, since I'm using this on a trainer in the winter the speed is pretty important.

It took me a while to figure out how to install and get this thing to work. The instructions aren't as complete as they should be. A few things to take note of:

1) Make sure you synchronize the watch with the sensor before testing the sensors by going into "Configure" then "Sensors". You will select the "Speed/Cadence" option and select "Scan". I usually move the pedals around to get the magnets to pass by each other (not sure if it will synchronize otherwise. When successful, it will say "Scan Successful" or something like that.

2) Make sure that when you synchronize the watch ("Configure | Sensors"), select "Scan" on "Speed/Cadence" and not just "Speed" and/or "Cadence". I figured this out when I tested this on my brother's Garmin Speed/Cadence meter (yes, the TIMEX works with Garmin's ANT+ signal as well); and it only worked when scanning using "Speed/Cadence".

3) You pretty much have to make sure the distance tolerances are met as specified by the instructions. It's possible the chain stay is too far from the crank for it to work. You can tilt/move the cadence sensor closer to the crank as was needed for my Giant Trinity bike. You can also turn the speed sensor to tilt inwards to meet the 3/8" (10mm) distance tolerance requirements.

4) Make sure there is a battery inside the sensor. It should be the flat shiny side out towards you when you open it.

5) If you still can't get this unit to work, try using another ANT+ standard cadence meter. I know my TIMEX GPS watch works with my brother's Garmin Speed/Cadence sensor on his bike (also a Giant Trinity bike).

I am liking that I can see my cadence along side my heart rate, speed, and altitude. BTW, when my speed/cadence sensor is on, my watch is still recording GPS location as I found out the first time I analyzed my test workout on trainingpeaks.com.

I have reinstalled this thing several times - the cadence sensor works fine - but the speed sensor doesn't work at all. It seems others are having the same issue - save your money - avoid this piece of junk. My simple Cateye speedometer works every time and instantly.

The other problem is when the Timex Global Trainer finds the Speed & Cadence sensor, the watch won't use the GPS function to give you your speed anymore. You can't simply use the cadence function by itself.

So, I find myself incredibly frustrated - I've ordered the Garmin speed and cadence sensor which, by the reviews, seems to be more reliable.

Again, avoid this horrible product.

Only tried to use this once, shows up on my Timex Global Trainer as Speed and Cadence Sensor. Only getting cadence output with no speed data, since I'm using this on a trainer in the winter the speed is pretty important.

The cadence speed monitor would not pick up the signal consistently and did not fit well on my Giant road bike.

i had been reading about all the comments saying that this does not work at all. but the truth is that it really works. all the trick is about the position (distance) of the sensors. the distance between the sensors and the magnets should not be more than 5 mm. not 10 mm as the manual says. for the first time to get recognize the sensor , you have to put really close sensors to the magnets and at the same time enable the scan function in the clock. then you can install the sensors

I still have not been able to record anything with this device. I have followed the instructions, but the device is not capturing anything. Pretty disappointing....

I wish I could have give it a negative star rating since it didn't perform according to the description just as all the other reviews has described here. You either get the cadence or speed reading. Both never both together. Would urge Amazon to feedback Timex on this issue, as it doesn't reflects well for Amazon to retail a faulty product and Timex to put out a half baked device out in the market. Judging of the lack of articles from Timex web page, i guess they have not been spending time to resolve this issue. I am rather curious to find out how some reviews mentioned that the device had worked perfectly fine for them. Does this implies the device comes from a production line that output with 50% failure rate? Until Timex is able to resolve this issue, I will not recommend you to consider purchasing it.

Take time to install and the cadence sensor is difficult to set. The cadence is not function after 2 weeks. It seem the sensor is broken.
