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.

Very cool
It’s a very nice watch. Friend made fun of me that it’s very army vibe but I like that. If you are buying it for the digital aspect it’s very tiny. The analog is more prominent and the digital time is small sometimes even hard to tell if the time hands are blocking it To set the time I had to YouTube it; after a few tries I figured it out. I only took off one star because the digital Time is smaller than expected I really love the watch and plan to wear it for daily use Was also surprised the date was accurate when I turned it on

Great watch I like the smaller size, it fits more like a normal watch. Just had to change the strap out.

I wanted a rugged watch for an upcoming vacation to Costa Rica. This watch is in a reinforced case and waterproof. Easy to read and comfortable to wear. I like it!
