I've had this watch for about 4 or 5 years.

It measures:
  • Time - receives atomic time radio signals 6 times per day so it's very accurate
  • Temp - It takes 5 to 7 minutes to get an accurate reading if you've been wearing the watch. You need to take it off for a temp reading but it's fairly accurate. I've measured it against my Kestrel weather station and it's always pretty close.
  • Altitude - Also fairly close. It may calibrate itself with the built in barometer
  • Barometric pressure -
  • Direction - built in digital compass
  • It's got a shitload of timers, countdown timers, alarms, time zone settings, calendar, memory features, etc...
It's a little on the large side but not as big/bulky as I expected it to be. The biggest problem with this watch is remembering how to use all the functions without referring to the manual. Another issue is the band. It's durable and comfortable...but for me, the adjustment holes are slightly off. One hole is too loose, the next is too tight. There's really no way to adjust it so I just live with it. And, it's not bad, just a minor annoyance as I don't like a watch that moves around on my wrist. But the other option, which is just as annoying, is having a watch that's too tight.

I've never needed it in a survival situation but I can see where it could be very handy. I was a weather forecaster in the Air Force for a while and I've actually attempted to make very basic, very short-term, weather forecasts with it...with some pretty good success. It's easy to tell when you've had a frontal passage and so forth so you can make educated guesses as to what the weather might be for the next few hours or at a minimum, what can be expected. It can help to alert you to potential weather problems with just some basic weather knowledge.

It is very durable and reliable. Mine's been beat around pretty bad on occasion and hasn't shown any ill effects from the rough handling.

The big downside is the price. I got a deeply discounted price on it when I had my store and some vendor was trying to get me sell them. I declined but still got the watch. If I recall I got it for about $89. I think they sell today for a little over $200.
