GBM-2100CX-9ACR

G-STEEL
2100 Series
GBM2100CX-9A

Welcome 2026 with style. Celebrate the year of the horse with a very special G-SHOCK inspired by that powerful symbol of strength and beauty — the mythical “thousand-li” winged horse that can gallop 500 kilometers, or 1,000 li, in a day.

A fearless, heroic horse sweeps across the dial, the engraving of the mane flowing out onto a gorgeous gold-colored ion-plated bezel. The result is an extraordinarily dynamic, dimensional design. Gold-colored indexes symbolize the auspiciousness and splendor of the New Year, tipped with bold red that evokes the rugged strength of the thousand-li horse. Illustrations of the mythical equine on the case back and featured on the special packaging complete this classy celebration of the year of the horse.

The GBM2100 comes equipped with Smartphone Link and Tough Solar charging, all while retaining the slim profile for which the 2100 line is known.

Welcome in the New Year with a rugged beauty of a timepiece that delivers both toughness and aesthetics.
