I bought this for my wife, for something beatable to wear when horse riding, and after two years the band disintegrated.  It literally cracked and broke in half.  Inspection revealed several more cracks, and, sure enough, a gentle tug on the band broke it in a second place.  This wasn't a breakage caused by one mishap - it was a total materials failure caused by poor quality manufacturing.

As others have reported, this watch got scratched up, but so what?  A "sports" watch is going to get rough treatment, and I'd rather have a scratched plastic lens than a broken glass lens.  The band, on the other hand, needs to just work.

Now, most Casio watches have available replacement bands, but *not* this one.  A typical replacement band is in the price range of $10-$20, which is the price of this whole watch *with* band, which is probably why they don't bother selling just the band.  Fair enough.  But since that's the case, the band must be designed to last more than two years.

The only reason I can conceive for the band breaking down so badly in so short a time is from salty sweat corrosion, and a "sports" watch should be able to withstand salty sweat.  Hence the one-star rating: this watch simply doesn't live up to its billing.  Too bad, because before its degradation, it was compact, functional and attractive.

P.S. I've ordered a Casio from the "Baby-G" line, to replace it, as those are supposedly built to handle rough treatment (at three times the price).  Check back with me in two years.
