Striking black on silver projects G-SHOCK toughness: Monochrome design suited to a wide range of styles
Published on 15 December 2025
This collection is based on the GMW-B5000, GM-B2100, and GMC-B2100 — watches that inherit the iconic form of the DW-5000C, the first G-SHOCK. The top bezel, a defining feature of the design, is finished in black. Crafted from stainless steel, the bezel undergoes demanding processes of forging, cutting, and polishing to achieve a sharp, dimensional finish.
