Casio G-SHOCK 2100 Series – Model GM2110D-3A1

The GM2110D-3A1 brings a refreshing blue-green metallic dial to the iconic GA2100 silhouette — now elevated with a forged stainless steel bezel and stainless steel band. This model fuses the rugged spirit of G-SHOCK with a refined metallic finish, making it an ideal choice for both everyday wear and polished styling.

The cool blue-green gloss of the dial contrasts beautifully with the brushed metal bezel, adding depth and sophistication while preserving the toughness that defines the 2100 Series.

Design Overview

This model enhances the fan-favorite “CasiOak” form with a meticulously forged, cut, and polished stainless steel bezel, giving the watch a sharp yet understated presence. The uniform octagonal bezel maintains the iconic look but provides a more premium, modern feel.

Beneath the bezel is a high-rigidity glass-fiber-reinforced resin case, engineered for shock resistance while keeping the watch comfortably lightweight.

The dial features a glossy metallic blue-green tone — a breezily sophisticated color option that adds style without sacrificing clarity. Paired with the durable stainless steel band and one-touch three-fold clasp, this model is built for versatility, whether for work, travel, or daily wear.

Carrying the legacy of the first G-SHOCK, the GM2110D-3A1 remains committed to the brand’s core values: strength, simplicity, and durability.
