Independent Bezel

The watch features a stainless-steel bezel in a sophisticated shape. With attention to detail, even different facets of the same parts are uniquely finished using different types of finishing technique: hairline, mirror finishes and polishing process. This shows off an impressive array of metallic surface textures that captivate the eye from every angle.

Vapour Deposition Treated Dial

A power-saving module enables the use of an opaquer dial, and highly chromogenic dial colouration is achieved with multilayer vapour deposition. Vapour deposition is applied to the iconic G-STEEL dial indicator and bridge parts as well as parts of the face design, proving the meticulous care taken through the very last detail.

G-SHOCK G-STEEL GST-B400 Slimness & Energy-saving Module

Slimness & Energy-saving Module

Optimised, high-density mounting of the circuit board structure made it possible to slim the module. A substantial reduction in power consumption was also achieved by reducing the number of watch hands to two and adopting a low-power Bluetooth® system. The ability to solar charge with an opaquer dial allowed for a high degree of freedom in dial design.
G-SHOCK G-STEEL GST-B400 Carbon Core Guard Structure

Carbon Core Guard Structure

Offering strength, lightness and excellent weather resistance, a carbon fibre-reinforced resin case protects the module. Additionally, buffering components made of resin mounted between the upper and lower bezels help absorb external shocks. At just 12.9mm, this is the slimmest case in the G-STEEL line. The newly developed form of the button guards makes it possible to offer generously sized stainless-steel buttons even in this extra-slim design.
