The iconic, crazy-durable G-Shock stocked full of surf-focused data

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. A favorite among surfers, the GBX-100 is part of the G-LIDE line of G-Shocks. A multi-function digital display delivers tide, moon, and sun data to keep you informed on the water.
