gm-s2100b-8aer g-shock black dial

Show off a minimalist, clean, and bold look with the mid-size G-SHOCK in a metal-clad octagonal version of the original iconic design. Forged from stainless steel with a hairline finish and rounded cut, the robust bezel exudes exceptional style. Only the letters at the top and bottom are engraved, for a simple, one-piece design. The dial, flattened for slimness, is treated with ion plating and mirrored indexes to add brilliant depth. Choose your favorite look: rose gold bezel on a black strap, dark gray on a black strap, or silver on a green strap.
