Casio G-Shock Carbon Khaki Watch

Notable features include a carbon fiber-reinforced case, guardless buttons, front light button, a double case back structure, and multi-color resin bands. The Carbon Core Guard gives the GA-2000 a very light weight at 64 grams which is lighter than the GA-100. The display has a 3D index with high-contrast analog hands, LCD subdisplays, and a menu subdial.

Another unique feature of the GA-2000 is that unlike other G-Shocks the bands can lay completely flat with the case and are easily removable using a slide lever without special tools. Casio is reportedly planning to sell several bands separately including a Cordura fabric band, resin band, and Velcro band.

The GA-2000 measures 51.2 x 48.7 x 14.1 millimeters which is smaller and thinner than the GA-100 (55 x 51.2 x 16.9 mm). Other features include shock resistance, 200-meter water resistance, world time, 1/100 second stopwatch (24 hour total with split), countdown timer (24 hours), 5 alarms, hourly time signal, dual Super Illuminator LED lights, and estimated 3-year battery life. Blue and black bands with blue hands and accents.
