Uncompromising Strength Meets Sophisticated Design Experience the perfect blend of style, functionality, and durability with the G-Shock CasiOak Carbon Core Guard GA2100-1A1. As an illustrious heir of the original DW-5000C introduced in 1983, this watch evokes G-SHOCK’s timeless appeal while pushing the boundaries of resilience. Signature Octagonal Form This model sports the unique octagonal shape reminiscent of the pioneering DW-5000C. The classic analog-digital timekeeping is seamlessly integrated into a straightforward, clutter-free design, without compromising the iconic G-SHOCK toughness. Thin Yet Robust With the high-strength resin material reinforced with carbon fibers, this watch boasts an impressively thin case. At just 11.8 mm, it stands as the thinnest among G-SHOCK combination models, offering a sleek profile without sacrificing robustness. Featuring the exclusive Neobrite technology, the GA-2100-1A and GA-2100-4A models deliver enhanced visibility in low-light conditions. Carbon Core Guard Structure The innovative carbon core guard structure provides advanced protection to the module. By enclosing it in a carbon case, the watch gains exceptional strength, crack resistance, and durability. This case is constructed with fine resin infused with carbon fibers, affirming the watch's commitment to enduring toughness.
