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

Rating : - An excellent purchase
I bought this T5H881 HRM to help my wife began a training program. It is ease to work and it has all information she needs. She is so pleased with this product. The instruction manual was clearly written and easy to understand.
There are just enough functions for she without loading the product up with things she will never use. The use is simple and she can remember how to use it without having to refresh her memory by repeatedly rereading the manual.
The price was excellent. So, figuring out all these benefits in a Timex product I decided to buy one T5J31 HRM to me.
