G-Shock GA-2000: Sleek Analog-Digital with Carbon Core Guard

Utilizing the new Carbon Core Guard structure like the GWR-B1000 Gravitymaster, the analog-digital G-Shock GA-2000 series offers a new urban outdoor style with a sleeker look than the usual G-Shock and does it at an affordable price point.

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.

Despite the model number and the shared technology with the GWR-B1000, the GA-2000 does not appear to be a Gravitymaster model like the GA-1000.

The GA-2000 series is a March 2019 release in Japan and is priced at ¥16,000 JPY for the blue and black GA-2000-1A2JF or yellow and black GA-2000-1A9JF and ¥20,000 JPY for the red and black GA-2000E-4JR which also includes a swappable black resin band and khaki green cloth band. The GA-2000-1A2, GA-2000-1A9, and GA-2000E-4 will also be released in other Asian countries.

Update: Casio America also announced the GA2000-1A2, GA2000-1A9, and GA2000E-4. The GA2000E-4 is advertised as a limited edition and will include the black resin and green cloth bands in addition to the red resin band. The GA2000-1A2 and GA2000-1A9 are April 2019 releases with a list price of $130 USD each and the GA2000E-4 is a May 2019 release with a list price of $160 USD.
