This Bluetooth-connected G-Shock balances strength and smarts

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 protective bezel, the resin band, the serious water resistance—were all in service of that single goal. And ever since, G-Shocks have maintained their place at the pinnacle of durability while still looking stylish as hell. Unfussy and utilitarian, it’s a watch that can handle anything you put it up against. This new addition to their GBA series packs all the functionality you’d want from a smartwatch into an analog silhouette with the durability G-Shock has become famous for.

  • Memory stores step, distance, and calorie counts
