The Indiglo night-light uniformly lights the surface of the watch dial using patented blue electroluminescent lighting technology. It uses less battery power than most other watch illumination systems, enabling your watch battery to last longer. The Night Mode feature allows you to illuminate the Indiglo night-light for 3 seconds with any button press, regardless of the mode or function. The watch is water resistant to 50 meters (165 feet)--suitable for swimming but not for diving--and the GPS sensor is splash resistant. All Timex heart rate monitor sensors have batteries that can be replaced by consumers without requiring them to be returned to the manufacturer.

Rating : - 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.
