Add a touch of colour to your classic style — a full-metal G-SHOCK with vibrant blue dial. The dial is finished in metallic blue vapour deposition, adding a striking touch of originality to the iconic stainless-steel bezel and band design. Buffering components made of fine resin are installed between the bezel and case, with a three-pronged structure dispersing shocks to the band’s connecting pipes, to deliver all the shock resistance of a G-SHOCK in a full-metal timepiece. And the case back features a screw-lock construction to ensure a tight seal. The metal band pieces are dimpled to reproduce the look of the resin band design of the very first G-SHOCK. The stainless-steel bezel is meticulously forged, cut, and polished for stunning depth and dimension. A hairline finish is applied to the bezel top and a mirror finish to the beveled edges, creating a smart metal timepiece that truly shines.
