GBM2100CX-9A - Year of the Horse

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 GBM-2100 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.
