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.

Watch is nice overall. There’s a small gap between the band and case that is primarily noticeable because the watch and band is white.

It fits perfectly, probably slightly more comfy than my Hidden Coast Casioak (6.75' wrist) , it wears v well being lower profile than you expect. It definately has a softer strap and case materials. I love its bright yellow 'Danger' colours, to me it looks like it might have been born from get together of Robot wars and JCB :))... or maybe a mutant android Hornet ? Its just great, I love it, especially as its Bluetooth and now simple to set up , especially for travel etc. Shame its not Solar, that would be killer !
