The G-SHOCK G-STEEL GSTB400 epitomizes a blend of refined aesthetics and rugged resilience. Its striking all-black design harmonizes metal and resin elements seamlessly. The black ion-plated metal bezel contrasts boldly against a jet black backdrop, exuding a sense of sophisticated allure. The meticulous craftsmanship is evident in the diverse surface textures achieved through various finishing techniques, showcasing an attention to detail that captivates from every angle.

Technological prowess is a hallmark of this timepiece. A power-saving module enables an opaquer dial, while multilayer vapor deposition creates a vivid chromogenic dial coloration. This intricate process extends to the iconic G-STEEL dial indicator and bridge parts, underscoring the dedication to perfection in every facet.

Constructed with a carbon fiber-reinforced resin case, the GSTB400 strikes an optimal balance between shock resistance and lightweight design, resulting in the slimmest case within the G-STEEL range at just 12.9mm. Notably, the newly engineered button guards facilitate generously sized stainless steel buttons, even in this exceptionally slim profile.
