GGB100-1B Watch

Story

The iconic, crazy-durable G-Shock built for extreme environments, with a lightweight build and quad sensor technology

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. One of the latest additions to the Master of G series, this one is based on the Mudmaster model with maximum mud, water, and dirt resistance, adding lightweight carbon fiber to the case for an even lighter feel on the wrist.
