I have the full-black version and it looks like it means business. Joking aside it's a great stealthy-looking sports watch. Also, I got the watch as a gift from my wife so if you are looking to gift this, yeah, go ahead, I think any watch lover would love it in the collection.

The size is perfect for me, it doesn’t look chunky even though it's quite large and the band goes quite sharply downwards and not extending the effective “lug to lug” which helps a lot for smallish wrists.

The build quality is where I have some issues with it. After about 3 years of semi-regular wear, the outer shell has started to warp and get a bit loose. It's not as tight around the watch head as it was when new.

This is something that happened with an older G-Shock that I have as well. I’m not sure how common this issue is but it's something I noticed. The watch still holds together very well so it's not falling apart or anything but it is quite annoying.

Another issue I have with the watch is the lack of lume on the hour makers. I think it would have helped with legibility. Sure there is the usual G-Shock LED light but since there is some lume on the hands why not add on the markers as well?

Some anti-reflective coating would have been nice since at least in the full black version the dial is quite hard to see if light hits the dial. On other color options, it doesn't seem to be as bad. My wife’s GMA in the pink color scheme doesn’t have this issue.

Even though I mostly complained about the watch here, I still think it's a great watch for the money and also there are quite a few mod kits out there to change the look of it, cases, bracelets, and whatnot if you are into modding.
