The iconic, crazy-durable G-Shock built for extreme environments, with triple sensor functionality and a solar powered battery
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 GW9400-1B is the latest addition to the Master of G series of purpose-built watches for use on the job in extreme environments. Water- and mud-resistance, a lightweight resin case, and a full suite of functionality make it one you can depend on no matter where you take it.
