I really like G-Shock's designs, but they're most often far too large for my liking. I was about to finally pick up the G-2100 "Casioak" this Xmas, but then I saw this new design & immediately forgot the Casioak ever existed. The additional angles on the bezel look a bit like armor plating, but the smaller (for G-Shock) 46mm size still falls along the edge of tasteful watch size standards. And since the strap is integrated into the bezel, the watch wears much better than a 46mm should.As for features, this model has pretty much the same functions as most other G-Shocks: World Time, Stopwatch, Timer, Alarm, Bluetooth, etc., with the only really noticeably missing feature being Solar power. The negative digital display is a bit better than on other models, but still ... MoreI really like G-Shock's designs, but they're most often far too large for my liking.

The negative digital display is a bit better than on other models, but still not quite clear enough to be able to read the time/date/zone/etc. at a glance. And the Light feature, like most G-Shocks, is really just adequate.Other than the small digital display, light function, and lack of Solar, I'd say this is an excellent entry-level G-Shock. It's packed with features, affordably priced, and it'll fit on just about anyone's wrist. I ultimately chose the matte black version, but I think this design will look great in whatever color you choose (or Casio chooses to make over time.)
