Wow, where to begin with this thing. I purchased this watch back in January of 2011 and wore it maybe a total of 6 times while hiking, playing golf, and general outdoor type stuff. The first thing I noticed about the watch is while on the wrist the buttons will get pressed anytime you articulate your wrist (casio pathfinder PAG240's fixed this by having shrouded button covers on the bottom side). Not a huge issue but still kind of annoying. Second, the negative face is definitely cool looking but only practical in bright daylight (night time forget it and the back light is weak as hell-even with a new battery). Third, the strap is waaayyyy cheap-o and the spring bars are extremely tiny. Fourth, you better like changing batteries about every 8-10 months and be very careful screwing the case back on because the threads are very easy to cross! Fifth, the issue of water resistance is up to web browsing hear-say where everyone seems to voice an opinion that you can scuba-dive with this thing, but in actuality it's barely rated at 30 meters (really? why put a depth gauge on this thing for 30 meters?). Of course the above items are minimal issues, but the biggest gripe happened while wearing the watch to work one day. One of my techs was using a porta-band to cut some steel and I was holding the end (drop side). The vibration of the cutting blade actually made my watch turn off! I opened the case back and could tell that the tension bar for the battery was just not enough to keep good pressure on the battery-super cheap. Needless to say I put a new battery in the watch, re-calibrated everything, and luckily it started working again. Scared to use the watch I put it on Flea-Bay and actually "made" money off this thing. For a top tier piece of "supposed" military gear I wouldn't waste 2 cents on this garbage. If I had to say one positive thing about this watch is it does look pretty cool and the ABC functions are relatively accurate. If I had to go into some serious s*&%, this watch would definitely be left behind....you have been warned!
