CASIO G-SHOCK GA2100RB-3A
The Casio G-Shock GA2100RB-3A is a limited-edition collaboration between Casio and Indonesian rapper Rich Brian (of the 88rising label). This special model takes the slim, octagonal GA-2100 “Casioak” design and reinvents it with bold colours inspired by a guitar Rich Brian cherished in his youth — a seafoam green base paired with salmon pink accents. The caseback also features Brian’s signature, making it a must-have for fans and collectors.
