ga-2100rc-1aer Classic Ga-2100 series

Add a touch of vigor to your look with a G-SHOCK featuring a design inspired by rusted iron that stands the test of time. These watches pay homage to G-SHOCK's ongoing quest for ultimate durability in neoclassical black and rust designs that evoke the sheer tenacity of rusted iron. The sepia tones, inspired by the textured look of rusted metal, pair perfectly with the basic black. Light blue accents lend a timeless style with a rustic touch.
