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 brandsâ€™ logos on top. Expect this pack to drop on Saturday, July 20, at Ron Herman in Japan and select retailers in Japan.
