Casio GA-2100RRB-4ADR

Indulge your passion for bold, bright toughness with an iconic G-SHOCK style in the vivid red loved by trendsetters and athletes the world over.

Introducing four iconic styles in G-SHOCK brand red: the ever-popular 5600, a direct legacy of the first-ever G-SHOCK; the 6900, a timeless cultural icon still loved by people of all ages; the 110 with strong, bold oversized case; and the streamlined beauty of the 2100 with octagonal bezel.

Treated to a vapor deposition finish in red, the watch face blends seamlessly with the red band and bezel, while the dramatic textural contrast exudes strength and intensity. The inverted LCD and touches of black incorporated throughout the design pop against the vibrant red color scheme, the black accents enhancing the impact of the overall design to convey the uniquely tough G-SHOCK identity.

Key resin components for the bezel and band are made with bio-based resin, a material expected to help reduce environmental impact.

These vibrant watches make a great accessory for your street-savviest fashions and your most casual styles.
