It is GST-B400XD which adopted the carbon bezel from the metal series "G-STEEL"
of the alarm toughness watch G-SHOCK.
Developed a carbon bezel that combines carbon fiber reinforced resin and carbon sheet based on GST-B400, which is a slimmer version of G-STEEL.
The band adopted a stainless metal band
Blue is used as an accent color on the dial to give a cool impression.
The base model GST-B400 realizes miniaturization of parts, thinning of modules, and power saving, and maintains high functionality of Bluetooth® and solar while reducing the thickness.
In addition, the carbon core guard structure makes it the thinnest size in the G-STEEL series (as of March 2021) while maintaining impact resistance.
In terms of design, by reducing the button guards to the utmost limit, we adopted a large stainless steel button that is slim yet easy to push.
Three-dimensional parts are used for the dial, and the finish is particular about the appearance.
The G-STEEL series combines toughness and design by fusing different materials such as metal, resin, and carbon.
