Casio G-Shock GA-800 Watches

About the Watch in short. Representative of the youth series GA in a small building. The watch has a compact display with one digital window, on which all the necessary information is placed. The hands are distinct and pointed, and the hour markers are large and made in a voluminous format, so there will definitely be no problems with the readability of the dial. For ease of use of all functions, it is possible to move the Hand Shift arrows so that they do not block the electronic panel. The GA-800 is sharpened under a stopwatch – it starts with one press of the Start button on the right side of the case and up to 120 laps can be stored in memory. A separate remote button on the front side is responsible for activating the backlight – two LEDs illuminate both the analog and digital zones.

Enjoy Japanese approaches to Tough and Functional Watches!

*some images are about G-Shock 5000/5600 cases, but the technology, approaches, concepts and philosophy remains the same for the whole G-Shock Model Range

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.
