Say hello to the fourth Rui Hachimura signature G-SHOCK!

Jump into the future of tough, rugged watches with this signature timepiece inspired by professional basketball player Rui Hachimura.

This collaboration model is based on the GBM-2100, with bold metal bezel, solar charging, and Bluetooth® connectivity. Touches of red — a G-SHOCK brand color that also evokes Hachimura’s passion for the game — are added to set off the gold color of the dial, which features a basketball-court motif. The black band highlights the watch face’s powerful impact and pulls the design together for a timepiece that projects focus and strength.

Hachimura’s original logo featuring the symbol 八 (hachi in Japanese, meaning “eight”) is engraved on the case back, and the side button at the 8 o’clock position is laser engraved with the hachi symbol, as well. These and other Hachimura-inspired symbols are sprinkled throughout the design, for a collaboration worthy of a true global basketball sensation. The shock-resistant construction you expect from a G-SHOCK in a design as sharp, sporty, and fearless as Hachimura himself.

- Comments from Rui Hachimura This G-SHOCK signature watch is a limited edition I produced for everyone who enjoys both sports and fashion. It's designed with my favorite colors and the black samurai logo. Please take a look at this watch and try it for yourself. 

Rui Hachimura

Born February 8, 1998 in Toyama Prefecture, Japan. After graduating from Meisei High School in Miyagi in 2016, Hachimura attended Gonzaga University in the United States. As a member of the Gonzaga University basketball team, he became the first Japanese national to play in a National Collegiate Athletic Association (NCAA) tournament. Hachimura received the 2018-2019 Julius Erving Award, which recognizes the top men’s collegiate small forwards of the year. He made history when he became the first Japanese-born player ever to be chosen in the NBA Draft, going to the Washington Wizards as the ninth overall pick. Hachimura joined the Los Angeles Lakers in 2023.

What to do with Broken Watches? 

G Shock Battery Replacement

G Shock battery life ranges from two to six years, depending on how often you use the alarm or the backlight. Frequent use of either feature drains the battery pretty fast hence, the need for replacement. The life of the replacement battery, on the other hand, depends on how long it has been sitting on the shelf. Its shelf life is ten years in room temperature after which it goes through gradual degradation.

G Shock Strap Replacement 

G Shock watches are known to last a lifetime, but the bands wear out after prolonged use. To replace them, place the watch facing downwards on a soft cloth, unhook the spring bars located at the base of each strap. Some models have the bars covered while others are exposed. Use a spring-bar removal tool to unhook and pull the band away from the watch. Repeat the process to remove the other spring bar. Replace them with the rod slots of the new band and use the spring-bar tool to fasten the bands. The procedure applies when replacing rubber straps. Metallic bands require a little tact hence, the need to engage a professional.
