The G-SHOCK GMA-P2110B-1A delivers casual sophistication with a stylish modern monochromatic color scheme. A metallic octagonal bezel ring catches the light along its inner and outer edges, shimmering subtly against the muted palette for an urban aesthetic.

Its compact profile provides a comfortable fit on slimmer wrists while presenting a refined look for any setting. Key components in the bezel and band are constructed with bio-based resin produced using renewable organic resources.

Engineered for everyday durability, this shock-resistant analog-digital watch features 200-meter water resistance, mineral glass, and double LED illumination for easy reading in the dark.
