Casio G-Shock Rui Hachimura GM-5600RH-1ER Men's • Special Edition • Black Metal Case

The Casio G-Shock GM-5600RH-1ER is the fifth signature model of professional basketball player Rui Hachimura, combining athletic durability with a distinctive collector's design. The striking colour concept pairs a powerful black base with passionate red accents — an expression of the strength and ambition Hachimura embodies on the court. The metallic components, including the characteristic bezel, have been refined with an ion plating (IP) treatment for a premium look and feel.

Hachimura's iconic "Black Samurai" logo adorns the dial surface and the case back. It combines the kanji character 八 (Hachi) with a Japanese sword, together forming the shape of an "H". His personal signature is additionally engraved on the metal clasp. The watch is delivered in an exclusively designed special edition packaging worthy of this collaboration model. The case is made from bio-based resin, underscoring the brand's commitment to sustainable materials.
