Review: Great watch for modding. - I really like the shade of blue on this watch, but it's a bit much for me. I used the dial as the base when I converted it from a resin case and band to the metal one from SKXMod. I also threw in white hour markers when switching everything over and I really like the result as I was going for a tiffany and co inspired look. The triple blue that it initially came with might be for someone with a more vibrant style, but I bought this knowing I was going to convert things just because of my own style. As far as G-shocks and watches go though, the GA-2100 is a solid watch and can be used beyond just the aesthetics. Recommend for those with bright styling choices or those that want to convert it.
Review: recommended - this was a gift for a friend she loves it
