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.

All Timex heart rate monitor sensors have batteries that can be replaced by consumers without requiring them to be returned to the manufacturer.

Rating : - FIrst HRM watch
I wanted to get a read on my heart rate during my runs and when I was at rest. My rest rate is very low. The watch is easy to use and set up. The actual Monitor fits around your chest and requires a little moisture in order to pick up the Electrical Signal that makes your heart beat. If it is on snug and moistened I believe the rate to be 99% accurate. I read a lot of reviews before pciking this one the one that caught my attention was how easy it was to start using it.
