Hi, I own this watch, well the jap built version, it's awesome.
If you can, get the built in the Japan rather than Thailand verson. You can tell by the model number and that its says on caseback where it's built. The jap built G's often appreciate in value, check WUS for all things gshock.
Here's a wrist shot on a 7.5in wrist.
Regular g's are decptively smaller than they look in photography but this one is bigger than most G's. It's tough solar atomic which means no batteries ever! It is one of the most, if not the most accurate watch in the world. This is my most favourite ever g-shock.
G-shocks are near to impossible to kill. have a look at the tests on youtube, you'll be amazed!
Oh and you never have to set this one manually. Great choice!
