This watch is the same as the Casio GW810D except for heavy duty resin bezel, buttons, and band instead of the GW810D's stainless and plastic painted to look like metal bezel, buttons, and band.
  This makes for a very versatile, tough, and fully featured watch that looks more rugged than the GW810D. As you have read elsewhere, the buttons take a bit of getting used too because they are so hearty, but pushing the buttons becomes easy once your subconsious takes over. My watch has seen the some of the same abuse that killed my non-Gshock watches and has come through w/out a scratch. Following the lead of some Gshock users, I've removed some of the bright paint used for lettering for a more subdued look.
  It has a great feature set. If you've ever had a Casio, you know how easy they are to learn to use. A feature I didn't think I needed, but have come to love is the auto el feature. It automatically flashes the light on for just over a second if you look at the watch in the dark.
  This watch is also cool because you can see the time of day when in in countdown timer mode.

This is a great watch if you want: solar charging, atomic time setting, world time, stopwatch, and countdown timer with a light. You can't go wrong with this watch. Looking for something more white collar? Try the GW810D.
