G-SHOCK

GM110RH-1A

Introducing the second Rui Hachimura signature G-SHOCK.
Bound into the future of tough, rugged watches with this signature timepiece inspired by professional basketball player Rui Hachimura. Breaking new ground in watch design with a metal forged bezel, this watch introduces a distinctive color palette to the base model — the metal-clad GM-110 analog-digital combination — for a truly original timepiece.
The design begins with the case, metal band loop, and buckle ion-plated in lustrous copper, and then adds yellow, green, and red, the national colors of Hachimura’s ancestral home of Benin, to the hands, dial and cloth band loops.
Switch between watchbands — classic black to make the copper case really pop, or the truly special kente-cloth* motif. Hachimura’s personal logo, which combines the Japanese character for 8 (八) and a Japanese sword, is engraved on the metal band loop and the back of the watch case.

*Kente-cloth: Kente are specially woven festive ritual cloths used in West Africa. Adorned with traditional proverbs and sayings, kente patterns boast a long cultural history.

Profile of 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. In his rookie season, Hachimura played in 48 of 72 games, and his stellar performance earned him a spot on the second-team NBA All-Rookie Team. The 23-year-old stands 203 centimetres tall and weighs in at 104 kilograms.

Structure

Metal-Covered Shock-Resistant Structure

The bezel is crafted with metal material. Minute protrusions on the inner case reduce surface contact with the bezel to cushion shocks to the module.

Glass Fiber Reinforced Resin Inner Case

Glass fibers are incorporated into the resin for increased strength. The material’s resistance to breakage and bending protects the module from external shock.

Forged and Molded Bezel

Undergoing about 20 forging processes, as well as cutting and polishing, the bezel is precisely crafted from a highly uneven molding to a back surface shape that determines the precision of its assembly.

– Hairline and Mirror Finishes [GM-110]

Circular and radial hairline finishes are applied to the raised and low portions of the bezel, and the slanted surface is polished to a mirror finish.

– Gold Ion Plating (IP) and All-Mirror Finish [GM-110G]

Mirror finishing is applied to the metal bezel. Gold coloration is achieved with an IP process.

Design / Function

Laminated Dial

The four-layer parts arrangement presents an impression of depth. Dimensional molding and metallic-toned coloration give the iconic Y-shaped part an ingot-like texture in its finish.

Hand Shapes

Large-sized hour and minute hands reinforce the impression of solidity with their simplicity. Crafted with particular attention down to the minute details, with features including punching and luminescence.

Band Design

The watch employs a simple, thick resin band. Industrial-style geometric patterns on the surface give an impression of depth.

Super Illuminator

High-intensity LED lights up the watch face with high-intensity light, maintaining watch readability in the dark.

Magnetic Resistant

JIS1 magnetic resistance is achieved with a magnetic-resistant plate mounted in the module. This prevents magnetism-caused hand deviation.

Battery Life of about 3 years

A newly designed module delivers power-saving benefits to achieve extended battery life of about 3 years, up from conventional models’ 2 years.


The large-case GA/M-110 analog-digital combination watch takes on a new look with the addition of metal elements that give the faces an industrial feel. The new design uses shiny metal for hour markers and the dial, in addition to the hour and minute hands.

Built from precision parts, the design of the GA/M-110 evokes the cool sophistication of Japanese manufacturing. The GA/M-110 has been sold in many color variations and, with its global popularity, captured first place.
