This is a great watch, except for two very annoying things.  First, the watchband.  What genius decided that a man's watch should have a band that catches and rips out arm hairs?  I mean, REALLY, did anyone with hairy arms actually test this??  There is a pivot where the band attaches to the case, and this pivot has a bit of the band that covers it.  But when the band flexes it opens and closes a gap there that perfectly catches stray arm hairs like a tweezers, yanking them out when you move your wrist.  I have a freaking BALD spot on my wrist now.  The second issue is with the compass... it needs calibration.  Well, that's to be expected really.  What I didn't expect is that the calibration procedure would be so time consuming, or that it would expire every 30 days.  Yeah, the calibration expires every 30 days, no matter what.  This pretty much ensures that, unless you use that feature often (and if you use it more than a couple times a month just buy a real compass - seriously) it's going to require calibration before you can use it.  Those two issues have turned this from a nice watch that I enjoy using to "that POS hair puller at the end of my arm that I wish would die so I could return it and get something else".

Update March 5, 2013:  The watch now sits on my dresser, never to be worn again.  Not only did it rip all the hair off my arm in that area, but I've now developed a blistered rash from it, something that has never happened to me before in 30+ years of wearing Casio watches with this band material.  Something obviously changed in the formula.
