I have owned other models of G Shock and Pathfinder watches.  This one is the best for my needs so far.  The altimeter is spot on accurate as well as the barometer and compass.  It is also sleek enough that I can wear it on a regular basis and not have people look and me like I have a desktop computer on my wrist.

I would definitely recommend this watch to anyone who wants functionality coupled with style.  The only thing it is missing is GPS,and that's no big deal.  Great job Casio, keep up the good work!
