GST-B400-1AJF

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 miniaturization of components and thinner modules have reduced its thickness while maintaining the functionality of Bluetooth® and solar power, and significantly reducing its 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, it features large stainless steel buttons that are easy to press. The standard model has a resin band and silver case, with different finishes on the top bezel and middle bezel for a different texture. The G-STEEL series is a fusion of different materials, metal and resin, and combines toughness and design.
