G-SHOCK and Rui Hachimura team up again for his fifth signature timepiece! This intense and rugged special edition is based on the GM-5600, with its distinctive metal bezel. Focused and powerful black is accented with vivid, passionate red — G-SHOCK brand colors that speak to Hachimura’s strength and intensity as he continues to soar to new heights. Hachimura’s signature “Black Samurai” logo graces the top of the face and the case back. The logo combines the kanji character 八 (hachi in Japanese, meaning “eight”), with an image of a Japanese sword, forming an “H” motif for “Hachimura.” His signature is also engraved in the metal band loop. Ion-plating applied to the bezel and other metal components adds special textural appeal and a refined touch. Key resin components used in the band are made with bio-based resin, a material expected to help reduce environmental impact. This special model comes in an impressive black and red color scheme along with the original packaging.
