The essential features of the PRW-3000 for me are its solar charging, atomic timekeeping and large clear display.  I need to see both the stopwatch and time of day at a glance.  Since people usually buy a wristwatch to see the time, it is disappointing that Casio engineers do not provide a time of day screen in all modes of all watches.  Compared to G-Shocks and other Pathfinders, the PRW-3000 is less cluttered with distracting writing and gauges, but still not restrained enough for business wear.  The watch can fit under many cuffs, and I have worn it for about two months in the place of a Mudman for robust athletic and outdoor activities, including weightlifting, skiing, running, biking and shooting. There has been no apparent damage to the case or any other adverse result.  Typically of Casios, the instructions for the compass are brief, clear and competent - much better than many found in published mountaineering guides and on websites.  Four stars instead of five because, as another reviewer mentions, the bracelet lacks the raised tab.  Also, like other watches with thermometers, that feature is inaccurate when a wristwatch is worn normally, on the wrist.
