CASIO G-SHOCK CARBON CORE GUARD Watch Battery replaced, operation confirmed. Backlight works perfectly. Luminous paint is bright. The olive green body and digital layout are cool. It has an army aesthetic, so how about it for outdoor activities, survival games, or street style? There are signs of use, scuffs, and scratches, but I think it has a good used feel. From G-SHOCK, the toughness watch that continues to evolve in pursuit of ultimate strength, comes a series that adopts the "Carbon Core Guard Structure" as a new shock-resistant structure. For the case material, carbon fiber reinforced fine resin is used, which exhibits high rigidity that surpasses the concept of resin while being lightweight. By preventing damage and deformation from impacts, it protects the module arranged inside. Furthermore, by making the back cover a double structure, it also guards against impacts to the back. The shock resistance of the button structure also realized an exterior design without button guards. In terms of design, a three-dimensional dial and large front buttons are boldly placed. It is finished with a tough design that gives off a powerful expression. This is the appearance of a model that combines a new shock-resistant structure that will be the next-generation standard for G-SHOCK and an urban outdoor style.
