G-SHOCK Unveils Fifth Rui Hachimura Watch Collaboration

A new limited-edition watch fuses sport toughness with Japanese heritage making every detail a statement.

G-SHOCK and NBA star Rui Hachimura have teamed up once again with the GM5600RH-1—a signature limited edition model launching September 2, 2025. This timepiece marks their fifth collaboration, reinforcing a partnership defined by resilience, personal identity, and a shared drive to challenge boundaries.

Bringing a Classic Back With Bold Style

The GM5600RH-1 builds on the iconic G-SHOCK 5600 shape, renowned since its unbreakable debut in 1987 for its square case and digital legacy. Hachimura’s version features a metal-clad bezel finished in sleek black ion plating. Pops of vivid red cover the bezel and digital markers, echoing G-SHOCK’s and Hachimura’s brand signatures. The case (49.6×43.2×12.9mm) and bezel mix resin and stainless steel for premium impact resistance.

A negative (inverted) LCD adds contrast, giving the display sharpness and standout visibility whether courtside or outdoors. The limited edition’s packaging is black and red, with co-branding that celebrates the partnership for fans and collectors alike.

The Black Samurai Logo and Cultural Identity

Embedded in this design is Hachimura’s “Black Samurai” crest: a motif that merges the Japanese kanji “八” (hachi, meaning eight, the athlete’s shirt number) and a samurai sword into an “H,” representing his name, heritage, and playing style. The logo appears on the watch face and case back, and Hachimura’s engraved signature adorns the metal band loop. As Hachimura says, “It celebrates where I come from and what I stand for,” making each watch not just a collectible, but a personal statement.

Athlete and Brand—Strength and Legacy

G-SHOCK’s collabs are known for both special packaging and fan experience. This new edition’s packaging continues that tradition, making it a true signature collector’s piece.
