7 Year Warranty Campaign Casio G-Shock G-Steel GST-B400 Series World Time Solar Men's Watch GST-B400-1ADR CASIO G-SHOCK G-STEEL GST-B400 Series Ana-Digi Black ◆From the toughness watch G-SHOCK, the G-STEEL GST-B400, which is slim and has an improved design, is now available. By making the components smaller and the module thinner, we have reduced the thickness while maintaining the functionality of Bluetooth and solar power, and have significantly reduced power consumption. In addition, the carbon core guard structure makes it the thinnest in the G-STEEL series (as of March 2021). It measures 12.9mm from the back to the top of the bezel, which is more than 1mm thinner than the GST-B100. In terms of design, it uses large stainless steel buttons that are easy to press. This is a standard model with a silver case, and you can enjoy the difference in texture by applying different finishes to the top and middle bezels. The G-STEEL series combines different materials, metal and resin, to achieve both toughness and design. Domestic model product number: GST-B400-1AJF
