Casio G-Shock GA-2000 Carbon Core Guard watch GA2000-1A9

Carbon Core Guard construction

The Casio G-Shock GA-2000 combines a carbon composite case with a resin bezel and band for a lightweight, shock-resistant sports watch. Its quartz movement drives both analog hands and a digital display, while mineral glass protects the dial. The 49 mm case fits adult wrists and the buckle clasp allows adjustment.

Sustained water resistance and illumination

Rated for 200-meter water resistance, the watch maintains its seal during prolonged swimming or diving sessions rather than brief splashes. The double LED light uses a Super Illuminator for both the analog face and digital display, offering selectable 1.5-second or 3-second durations with afterglow so the time stays readable in continuous darkness.

World time and timing limits

World time covers 31 zones across 48 cities plus coordinated universal time, with daylight saving toggles and city swapping. The stopwatch measures up to 23 hours 59 minutes 59 seconds, switching from 1/100-second resolution to 1-second resolution after 60 minutes. The countdown timer runs for 24 hours maximum, and five daily alarms plus an hourly signal provide recurring alerts.
