This is a great version of the PRW2500. I won't go into all the functions - many have explained these before. This is an ABC watch (Altimeter, Barometer, Compass) and it has a dual layer LCD display Casio has done a great job improving the displays for the dual layer watches and this one is crisp. It is a solar and atomic watch and it syncs very well here in North America (much more frequent than my Riseman does). While a big watch - it is relatively thin and wears very well - it looks much smaller on the wrist than you would expect - so it will not look like you have a huge monstrosity on your wrist. Resin band is comfortable and I have had no issues.

What i like most about the watch is the nice, think green metal ring - it adds a subtle bit of color to the all black watch that I just love. No crazy colors, but a watch that means business. Overall - a great ProTrek.
