Review title: Black X3HR
Product review: The watch is of good quality and does the things it says it will do. When I purchased this item, I was under the impression that it calculated altitude. It actually displays altitude based upon barometric pressure. The user must give the watch a baseline altitude for it to function correctly. Also, somewhat significant weather change can cause your altitude to display incorrectly. Perhaps this is a common way of measuring alititude, I don't know. I suppose for the utmost accuracy you'll need to go with a GPS enabled model. Overall, this watch is still a great product for the price, just be aware of how the product works.
