About the Watch in short. The newest representative of the GA budget series for youth. The case protection is based on the Carbon Core Guard concept – Casio’s latest technology for using carbon fiber in the watch case for more reliable protection of electronic parts of the watch. The double back cover is a fiberglass-reinforced polymer panel and a classic steel plate underneath. Engineers have provided the ability to quickly replace the strap using a special lever. A fully straightened strap in the horizontal position of the watch makes it possible to shift part of the shock load to the polymer case back. The basic functionality is fully consistent with the cost of hours – a stopwatch for 24 hours with an accuracy of 1/100 of a second, a countdown timer, world clock, 5 independent alarms and a calendar. Water resistant to a standard level of 200 meters.

Enjoy Japanese approaches to Tough and Functional Watches!
Carbon Core Guard structure. This new shock resistant structure protects modules with a carbon fiber reinforced resin case.
Exterior that uses a dual-layered case back. The panel back and back cover use a dual-layer case back. This alleviates shocks to the rear surface on the back cover, and allows the wearer to attach bands that can be laid flat.
Dual-layered case back. GA-2000 features a stainless-steel panel back that keeps the watch airtight, as well as a fine resin glass fibre case back that makes it tough against shocks.
Slide lever type bi-color moulded band. The bi-color moulded band can be replaced easily by operating a lever at its base.
Disc dial. A complex disc dial at 9 o’clock indicates the current watch mode.
Super Illuminator (high-brightness LED). The Super Illuminator function lights up the dial and LCD with high-intensity light, maintaining watch readability in the dark.
Large front button. A large button placed at the 6 o’clock position on the case activates the light and accentuates the rugged design.
Hand retraction function. When the hour or minute hand overlaps the LCD, it is temporarily retracted to ensure visibility of the date.
Shock Resistant. Shock-resistant construction protects against impact and vibration.

— Dual Back Cover (GA-2000 features a stainless-steel panel back that keeps the watch airtight, as well as a fine resin glass fibre case back that makes it tough against shocks)

Official Marketing Focus from Casio
From G-SHOCK, the watch that is constantly testing new limits in timekeeping toughness, comes a new series with Carbon Core Guard structure, which takes toughness to a new level.
The case is made of fine resin that incorporates carbon fiber for light weight along with rigidity that is superior to that of resin. This material protects the internal module from shock-induced damage and deformation. The dual back cover protects the back surface against impact.
Button structure shock resistance has been improved, which eliminates the need for external button guards.
The face of the watch consists of a disk pointer and raised hour markers for a look of bold toughness.
This new standard bearer of the G-SHOCK lineup combines a new shock resistant structure with urban outdoor styling that reflects its toughness.
