I had purchased a 225 dollar tritium traser code blue, but i have come to an epiphany that any quartz mechanical type is really not worth that much money. There is just so little it really does. But the casios you get so much function for such a small price in comparison, and the LCD quartz last longer anyway. The big issue i can see with this one is that the band is a unique design that employs  a metal clamp that the spring bar fits into and the watch case has a small area in the middle of it that the spring bar goes through. My work around was using a Chums the band Velcro and putting a small dab of super glue on the middle of the spring bar then pushing the watch into the center so it would not move back and forth. I will see if i can upload a picture or two to demonstrate what you will have to deal with if you buy this watch. The calibration of the temp. and compass is a bit tricky, but you will need to do it, to get a temp reading that is more realistic than measuring the temp of your arm which will show about 8 degrees higher than ambient actual. when you do the compass calibration don't do it in a vehicle, too much electronic interference (metal magnetism) to get an actual northern fix. do it outside away from metal fixtures and power lines and poles....
