The Madness x G-Shock DW-5000MD-1 is actually based on the current DW-5000 replica of the original 1983 G-Shock DW-5000C featuring a screw-lock case back. This is a model we usually see as the base for G-Shock anniversary limited editions and it is rarely used for collaborations. The DW-5000MD’s screw-lock case back is engraved with a Madness logo, and the band is dark green. A custom black and olive green box and tin case round out the package.
