Whether you slept on the mastermind JAPAN x Casio G-Shock previously, or they were unattainable last time, this will probably be the final opportunity to get your hands on these watches--except on eBay, of course. The two Japanese giants are teaming up for the last time to commemorate the three decades of Casio G-Shock. Included in the three-watch set are the DW-5600, DW-6900, and G-100 models, coordinated in matte black exterior with mastermind JAPAN logo on the face. These timepieces come packaged in a custom-made box, stamped by the two brands’ logos on top. Expect this pack to drop on Saturday, July 20, at Ron Herman in Japan and select retailers in Japan.
