Based on the popular tough solar model, G2310 introduced back in 2001, G-Shock introduces a new solar atomic version, the GW2310. Now updated with multi-band atomic timekeeping, it is more powerful than ever while retaining the classic, utilitarian case shape of its predecessor for clean yet rugged styling.
