Introducing the GM-2110D — an analog-digital combination G-STEEL based on the GA-2100, now with a stylish metal bezel and band update. Meticulously forged and polished, the uniform octagonal stainless-steel bezel anchors a simple, no-fuss design with a sophisticated, yet tough look. Made of high-rigidity glass-fiber-reinforced fine resin, the case is the slimmest of all G-SHOCK combination models, at just 11.8 mm. The metal band, together with a pop of fresh color from the metallic brass dial, is up for anything — work or play. Choose from, sky blue, orange, or lime green, in addition to classic hues of navy and silver. All with high-brightness double LED light, ensuring an easy read even in the dark.
