Design and build
The GM5600RH-1 marks the fifth Casio x Rui Hachimura collaboration and leans into a stealthy, sport-forward look. It features a black digital display with orange and red text, framed by a dark surround with red accents. Hachimura’s Black Samurai emblem appears on the watch, cleverly merging the letter H with the Japanese character 八 (eight), a nod to his jersey number. A black stainless steel bezel pairs with a durable resin case and band. Dimensions are 49.6 x 43.2 x 12.9 mm (about 2.0 x 1.7 x 0.5 inches), and the watch weighs approximately 80 g (2.8 oz).
