Great watch! looks very sharp, keeps accurate time, packed with survival features that do not require internet access (compass, barometric pressure, altitude, ambient temperature, pedometer, timer). Took me a couple of hours to set it all up, calibrate tbe barometer, thermometer, and altimeter, but once set up all features are reliable and accurate. Printed instructions are OK, found a few places where information was missing entirely, but I was able to stumble through. Watch is very intuitive once you get used to the button functions. The dial is kind of hard to see in dim lighting, but in bright light or when the backlight is on it reads clearly. adjustable screen contrast helps out with the visibility. watch strap is kind of cheap but I am replacing it anyway, and it is a standard 22mm lug strap. So far I am loving this watch. I can't wait to wear it camping or hiking. after wearing this watch for about a month I have to say that it is pretty awesome! the timekeeping is excellent, the altimeter is spot on, the pedometer is super handy, the compass works great, and the backlight is just bright enough to see in total darkness. Took some doing to set it all up, but once I got the hang of it it's actually quite intuitive. I wanted a watch that had smart watch features without requiring internet access, and I have worn it on several hikes in woodsy areas with bad phone service and it works great! Watch looks very cool, but the strap it came with was cheap so I replaced it with a green elastic strap and it wears quite nicely for such a big watch. only things bad i have found are that the compass gets wonky when you're around magnets (power tools, speakers in my car, etc.), and that the altimeter does not auto adjust for barometric pressure, so over time it loses calibration (I just recalibrate it to a k own way point before use). I love it!
