From the toughness watch G-SHOCK comes the GST-B400, a slimmer, better designed G-STEEL.The GST-B400 is the thinnest G-STEEL watch in the G-STEEL series, and its miniaturized components and thinner module reduce its thickness while maintaining the functionality of Bluetooth® and solar power, and significantly reducing power consumption. In addition, the carbon core guard structure makes it the thinnest in the G-STEEL series (as of March 2021). From the back to the bezel top, it is 12.9 mm, more than 1 mm thinner than the GST-B100. In terms of design, large stainless steel buttons are easy to press. The case and band are coated with black IP, and the dial is decorated with blue vapors, while the different finishes on the top bezel and middle bezel allow the wearer to enjoy the difference in texture.The G-STEEL series is a fusion of different materials, metal and resin, and combines toughness and design.
