Customer Review: Great watch!

Excellent watch! Very accurate GPS that tracks pace well and does not lose signal. As mentioned, it does take a few minutes to link up the GPS, but once it is linked up, it works perfectly. My only complaint is that it is a unisex watch - but the wrist strap is pretty big for a medium frame woman. As a woman, even the smallest size is a little bit loose. I contacted Timex to see if I could exchange the wrist strap for a smaller one, and apparently the wrist strap it comes with is the only one that fits on the watch. In the end I decided I liked everything else about the watch so much, that I didn't mind a little slipping around.

Customer Review: Just not very accurate

I have been using this product for the last month on marathon training runs. I find that the GPS is not very accurate and the distance measure tends to drift high. For example, on my last 20 mile run the GPS was off by about 1 1/2 miles; it was accurate for some of the trip but gave me readings too high on certain segments. (I was running along a river with little interference from trees or large buildings so I don't have an easy explanation). Other than that the heart rate monitor works fine and the watch functionality is good.
