Update 4/20/2012:
4 years later, everything is still working like new and the battery is still going strong. The screen is like scratch proof, not a single scratch on it even though the bezel got beaten up. But the watch band broke. A Casio brand replacement band costs almost as much as the new watch. So I am ordering another one.
