This watch has more features than most g-shock watches and its way more user friendly,this watch is so tough,i beat it daily at work and it shows no sign of wear! its dunked in water all through the day,jarred,bumped and banged and it looks like new still and the digits are bigger than the g's (big plus for us over 40 guys),hands down my favorite watch and it"s loaded with lots of cool features: time,day,date,month,a.m. p.m. indicators,3 time zones,compass(works dead on!)stopwatch,timer,occasion reminders,hydration timer,200m water resit,shock resist,and indiglo night lite with night mode,and worth every penny. As a hunter and fisherman,this watch helped me get back to my truck after getting turned around in the thick florida woods on a  small game hunting trip,this is a useful feature that worked in a real world situation unlike casio's useless temp. and barometer watches that have to be off your wrist for 20 minutes to even read close. Another big plus over the g-shock watches, is the price,a watch with this many features from a casio g model would be well over a couple hundred bucks or more!(like a frogman model)i.m.h.o.this thing should be military issue! its that good,hope this review helps.
