Welcome in the Year of the Snake with a special edition G-STEEL crafted at the intersection of metal and resin. Celebrate 2025 with innovative form and design inspired by the ancient ouroboros. This slim GST-B400 features an ouroboros motif, the ancient auspicious symbol of a serpent eating its own tail, representing infinity and immortality. This special timepiece pairs a silver-colored metal bezel and black watch face with gold-colored accents for a design that takes you smoothly from casual settings to formal occasions and back again. The side buttons and strip across the face from the 3 o’clock to 9 o’clock position add textural appeal with a snake pattern touch that nods to the Year of the Snake. The case back is engraved with a special ouroboros illustration representing infinite possibility. The GST-B400 brings together smaller components and a thinner module to deliver an even slimmer profile, while still offering the Bluetooth connectivity and solar power charging you want for greater convenience and significantly less power consumption. Add to this the watch’s Carbon Core Guard structure, and you have the slimmest G-STEEL yet (as of December 2024), measuring just 12.9 mm from case back to bezel top, over a millimeter slimmer than the GST-B100. Passionate attention to the smallest details — with large, easy-to-press stainless steel buttons, a resin band, and silver metal case featuring different finishes on the top and middle bezels — achieves an elegant, transformative look worthy of the Year of the Snake.
