So how does this sub-$100 watch manage to charm like the best of them? To start, it's the thinnest G-Shock currently in production. The case is 11.8mm tall, and even more, it wraps around the wrist in a way that makes it feel even thinner. Its plastic case is practically weightless if you're used to wearing an even a modestly proportioned 316L case. By design, the strap is angled down so that there's little room at any point between the 48.5mm case and the watch. There’s something else notable about the case, and that's the Carbon Core Guard tech that's incorporated. The case is constructed with a thin layer of carbon fiber in order to bolster its strength so the overall amount of material used in the case can be decreased, without sacrificing any sort of material strength. The Carbon Core Guard doesn't change the feeling on the wrist, but it does inspire a sense of confidence that the watch would be fine even if it were run over by a car. There’s a reason why G-Shocks are often worn by military and law enforcement personnel.
