Casio G-SHOCK Rui Hachimura Signature Men Analog-Digital Watch - Black | GBM-2100RH-1ADR
Casio G-SHOCK Rui Hachimura Signature Men Analog-Digital Watch - Black | GBM-2100RH-1ADR is a special collaboration model inspired by professional basketball player Rui Hachimura. It features a gold basketball-court dial, Black Samurai logo, octagonal stainless-steel bezel, Tough Solar power, Bluetooth Smartphone Link, and 200-meter water resistance.
Casio G-SHOCK Rui Hachimura Signature Men Analog-Digital Watch - Black | GBM-2100RH-1ADR is the fourth signature collaboration between G-SHOCK and Rui Hachimura. Based on the metal-covered GBM-2100 platform, it combines the iconic octagonal 2100 Series profile with basketball-inspired details and connected everyday functionality.
The gold-toned dial features a transparent wood-grain pattern designed to resemble a basketball court, while the black-and-red LCD draws inspiration from the sport’s 24-second shot clock. The Japanese symbol 八 appears at the eight o’clock position, and Hachimura’s Black Samurai logo is engraved on the band loop. His signature is also engraved on the yellow-gold ion-plated case back.
The watch combines a stainless-steel bezel with a bio-based resin case and band. Shock Resistant construction and 200-meter water resistance provide dependable durability, while Tough Solar charging supports long-term use without regular battery replacement. Bluetooth connectivity links the watch to the CASIO WATCHES app for automatic time adjustment, easy settings, reminders, Phone Finder, and access to approximately 300 world-time cities.
