GBM-2100RH-1A

Welcome to the fourth G-SHOCK signed by Rui Hachimura!

This exclusive watch inspired by professional basketball player Rui Hachimura is a leap into the future of durable and rugged watches.

This collaboration model is based on the GBM-2100 case, with metal bezel, solar charging and Bluetooth® connection. Red, the G-SHOCK brand color that also evokes Hachimura’s passion for the game, was added to enhance the gold color of the dial, which features a basketball court motif. The black strap highlights the contrast of the watch face and brings the design together for a timepiece that exudes focus and strength.

The original Hachimura logo with the 八 symbol (hachi in Japanese meaning “”eight””) is engraved on the case back, while the side button at the 8 o’clock position is laser engraved with the hachi symbol. These and other Hachimura-inspired symbols are scattered throughout the design, for a collaboration worthy of a true global basketball phenomenon.

The shock-resistant construction you expect from a G-SHOCK in a design as sharp, sporty and fearless as Hachimura’s.

– Comments by Rui Hachimura
This G-SHOCK designer watch is a limited edition that I produced for all those who love sport and fashion. It is designed with my favorite colors and the black samurai logo. Take a look at this watch and try it for yourself.
