This watch is no larger (maybe a little thicker) than other big-faced watches.  I am 5'7" and this watch strap fits perfectly.  As far as the set up, it took me about 15 minutes -- if you've had a casio watch before, it's simple as pie.  The digital face has the largest time you can imagine; comperable to the Timex weekender.  Before starting -- get your latitude and longitude.  Sure, it's not a girly watch, but it's perfect as an outdoorsy watch.  If you camp or hike -- or if you want a terrific silent buzzer alarm, this watch is perfect for you.  Also, it gives the sunset and sunrise time -- shows the moon (great if you're a gardener) and has 5 alarms and a light.  What's not to like?  I have lots of girly watches, but honestly, this is my favorite because it's so practical!  I wear the other ones during the day -- this one at night to wake up by.  I will use it hiking this summer and with other outdoor activities.
