I bought this watch to replace my old one that I lost. I must say that I had high expectations for this watch based off the solid reviews but this watch is mediocre at best. The watch's multifunctional nature is offset by the fact that it doesn't do anything particularly well. The thermometer is inaccurate even after calibrating, the compass display doesn't stay on for more than a view seconds after pressing the button which forces the user to press it multiple times--literally, every few seconds--when used for navigating, viewing different timezones requires that the user change a host of basic settings, and, worst of all for me, the armband is made of stiff plastic that doesn't mold to the user's wrist. All in all, like a jack of all trades, this watch can do a bunch of stuff but it doesn't do anything particularly well. I would recommend another watch for this price.
