Review: Great watch for wife - My wife wanted another G shock but she doesn't like Baby G shocks and she wanted something that was fitting for her work place. She saw these come out and she liked the black one. I bought it as a gift and it 100% met her expectations. It's a good size for a small wrist. It doesn't say Baby G on it which is a turn off for some people. The black is a nice shade for a clean look and the rose gold like accents give the watch a little something so it fits in well in a work environment and jewelry coordination. If it was like the all black larger version it would be too tacti-cool for some settings. It's super light and it reads well. This watch definitely fulfills every bit of its specs, advertising and online appearance. Sometimes it's hard to tell how a watch will look in person and on the wrist but this one was spot on. If you are liking it but are unsure, spring for it. It meets the hype, and some.
Review: Rugged but elegant - Beautiful watch and works great.
