Casio G-SHOCK 2100 Series – Model GM2110D-8A

The GM2110D-8A brings a premium metal upgrade to the iconic GA2100 design — now featuring a forged stainless steel bezel and a sleek stainless steel band. This model blends the beloved octagonal form with a refined metallic finish, delivering a stylish yet rugged timepiece suited for work, weekends, and everything in between.

Its steel gray dial adds a cool, understated sophistication, while the reinforced resin case ensures the shock resistance G-SHOCK is known for. With its elevated materials and classic 2100 silhouette, the GM2110D-8A is the perfect fusion of toughness and modern style.

Design Overview

The GM2110D series enhances the legendary “CasiOak” profile with a forged, cut, and polished stainless steel bezel. The octagonal shape stays true to the original but gains a premium metallic presence, making the watch feel more substantial and refined.

Beneath the metal bezel, the case is made of high-rigidity glass-fiber-reinforced resin, providing strength while keeping the watch lightweight enough for daily wear.

The glossy slate-gray metallic dial adds depth and legibility, and the stainless steel band with a one-touch three-fold clasp reinforces the model’s modern, durable aesthetic.

This model faithfully carries forward the spirit of the very first G-SHOCK—offering toughness, clean lines, and functional simplicity upgraded with premium materials.
