Taking the industry by storm in 2019, the GA2100 series pushed the bounds of design by offering a thin watch with an octagonal bezel and legendary G-SHOCK protection. G-SHOCK then revolutionized the series by adding a stainless-steel bezel, forging the GM2100 series. Always innovating, G-SHOCK then added Bluetooth® connectivity and Tough Solar charging to craft a steel watch beyond compare: the GBM2100 series stainless-steel watch. G-SHOCK G-STEEL combines sophisticated style with peace of mind, crafting steel watches with durable shock resistance and 200-meter water resistance (wr 20 bar). Going the extra mile, G-SHOCK manufactured the watchcase and band from bio-based resin, a material thought to reduce environmental impact. Conscientious at every level, that’s G-SHOCK G-STEEL.
