This watch is fantastic! User replaceable battery, sunrise/sunset times for many locations, altimeter, barometer, compass, thermometer, two time zones, stop watch and countdown timer. Also a storm alarm and backlight. This thing is spot on accurate underwater with temperatures, and I almost forgot its quite accurate depth meter. Not a professional diving watch, but anything above 30 meters and you are golden!!! No better watch for the money, this thing does it all SUPER WELL. If you love the outdoors @ all this is the wristpiece for you. Also its seen 140 degrees in Arizona (on accident in the sun) and its never had a problem...

This thing is a POWER HOG!!! I've gone thru three or so batteries in owning it for about 2 years, thank God it has a "user" replaceable battery. It only takes a nickel or coin of similar size to open and close the battery cover while RETAINING it's watertight seal.

I must attest this thing is very comfortable and LARGE! The silicon or rubber strap that comes on it is supple, strong, light, and very comfy! If you want a watch that does it all this is it, plus it comes in many handsome styles. I currently own the all black "military edition" but I would not mind the all black with a hint of red or orange, that'd be SEXY!!! Anyways, enjoy this watch, it will keep you on track literally. Oh and if you go camping or whatever, just bring an extra 2032 lithium watch battery just in case. Hope you enjoy this wristop computer!!!
