I own five or six watches and this is the only one I wear anymore.  I don't think it's too much hyperbole to say that it's the best watch on the planet - for any amount of money.  I suppose that if all you want is wrist bling, then maybe you should go elsewhere, but if you want features and function, this is the watch.

It synchronizes the time, it has a compass, barometer, thermometer and altimeter.  I use the compass and altimeter frequently, and that's a big reason this watch is indispensible.  The stopwatch is easy to access and the countdown timer is also very useful.  It's lightweight - especially for how many functions it contains.  There are so many cool features that it's easy to forget that it never needs batteries because of the solar charging.  It has an alarm and a backlight (and a handsfree backlight mode).

I travel across time zones quite often and it's really convenient to be able to just switch between zones.  I challenge anyone to find any watch to match up with this one. I'll buy another one of these as soon as Casio makes one with GPS and a depth gauge...
