Bought this watch from Amazon about a year ago, very good buy!
It has an activity monitor which is ideal for runners and walkers, gives calorie readings etc.
It also has a built in weather system, an altimeter and a temperature monitor (though like all watch thermometers only gives the temperature of your wrist!). The watch gives a barometric reading as well, useful for predicting the weather in the great outdoors.
Its seems durable as ive knocked the watch a couple of times (accidently!) and its still in perfect working order. The battery is really easy to replace, no screwdriver required!
Also has the usual features like alarm, backlight etc

Although the product title may lead you to believe this is a Heart Rate monitor it is not. It has monitors for altitude and movement, but not heart rate. Its only really of use for giving a rough estimate of activity when walking or running. Not much use in the gym or for cycling etc.
That said its a very nice watch, nice enough to wear all the time and would be useful if your chosen activity is walking or running.
