G-Shock G-Steel Solar – GSTB400-1A

The GST-B400 G-STEEL timepiece is a striking fusion of style and innovation. Encased in carbon fiber, it boasts an ultra-thin module, creating a remarkably slim profile at just 12.9mm. This design breakthrough doesn't compromise durability; the carbon core guard structure absorbs shocks while maintaining Bluetooth and solar power functionality.

With four distinct styles, including silver metal bands, dark resin bands, and vibrant dial finishes in red or blue vapor deposition, there's a choice for every taste. The bezels are meticulously treated, offering a captivating array of metal textures.

The dial features a power-saving module for an opaquer finish, and its rich chromogenic colors are achieved through multilayer vapor deposition. This attention to detail extends to the G-STEEL dial indicator and bridge parts. The case, crafted from carbon fiber-reinforced resin, ensures both robustness and lightness, resulting in the slimmest case in the G-STEEL line. The button guards are specially designed to accommodate generously sized stainless steel buttons, a testament to the meticulous engineering.
