GA100RC-1A Black & Rust Series Watch

Strengthen your look with G-SHOCK in a design evoking rusted iron that stands the test of time.

These watches pay homage to the undying G-SHOCK quest for the ultimate toughness in neoclassic black and rust designs evoking the sheer tenacity of rusted iron.

Sepia tones inspired by the textural look of rusted metal nicely complement the base black. Accents in light blue make for timeless style with a rustic flair.
