Enjoy Japanese approaches to Tough and Functional Watches!
Hollow case structure. Based on a realization that “shocks are not transmitted inside a bouncing rubber ball,” the structure was designed to let the module float inside the case, relieving shocks transmitted from outside. Today, the module’s shock resistance is realized through further technical innovations. But the revolutionary tough structure that gave G-SHOCK its origin began here.
All-directional covering. If the watch is dropped, the protruding bezel fully enclosing it absorbs the shock, protecting the buttons directly connected to the module and alleviating shocks from all directions. The bezel also guards the surface of the crystal. The band is curved stiffly at the point of connection with the case, moreover, enabling it to serve as a shock absorber and prevent direct shocks to the back of the case.
Protective cushioning of key parts. The crystal oscillator and other critical parts inside the module are guarded individually by cushioning material. Any strong shock to the watch causes immediate distortion of the cushioning inside the module, preventing contact failure and malfunction.
Japan Quality. Constructed with genuine quality, CASIO products provide truly practicable applications in which functionality and beauty combine. The leading-edge LSI technologies and skilled craftsmanship that give life to CASIO watches exemplify the quality Japan boasts in the world marketplace.
For CASIO, “faith in manufacturing” refers to an inexorable advancement of digital technologies and an uncompromising commitment to fine craftsmanship. This faith engenders unparalleled performance that not only elevates CASIO watches as close as possible to perfection, but that actually changes their wearers’ lifestyles.

The most distinctive specs of GM-2100 *Editorial
— Steel Casio Oak (popular octagonal bezel. Casio simply replaced the watch with a stainless steel bezel and case, making the watch more stylish and more weighty)
— Carbon Core Guard Structure (protects the module with a carbon case. Highly durable carbon fiber-reinforced resin is added not only to the center case, but also to the front and side button guards, providing even stronger resistance to shocks from above or below, or from any side)
— Stylish Look (for everyone for any style)
— 200-meter water resistance (good for swimming but not for deep diving)

Official Marketing Focus from Casio
Like other GM models (GM-5600, GM-6900, GM-110), the GM-2100 is based on its all-resin counterpart and has a stainless steel bezel. Considering the popularity of the GA-2100 series, a metal-covered “CasiOak” was inevitable, but we were not expecting to see it so soon.
