GA2100-1A1CR

Story

The iconic, crazy-durable G-Shock built for extreme environments

One thing mattered to Kikuo Ibe when he designed Casio’s G-Shock back in 1983: toughness. Everything we love about the iconic watch—the blocky shape, the encapsulating bezel, the serious water resistance—were all in service of that single goal. And sure, G-Shocks still hold their place at the pinnacle of horological durability, but they’re also stylish as hell. Unfussy, and utilitarian, it’s a watch that can handle anything you put it up against. The GA2100 is simple in its design but still packed with features, combining analog and digital timekeeping in their thinnest silhouette yet.
