Part of Casio's "New Rugged Basic" line, the GA-010 is the first G-Shock to offer a 10-year battery life. This major upgrade doesn't come at the expense of performance. The GA-010 delivers the full suite of core G-Shock functions, along with a Carbon Core Guard case and bio-based resin components that reduce both weight and environmental impact. This analog-digital hybrid includes world time, a stopwatch, and a high-brightness LED light that is easily activated by the large front-facing button, ensuring clear visibility even in low-light conditions.
