GM2100TTTR-8A

From G-SHOCK, the watch that has continuously evolved in pursuit of ultimate toughness since its debut in 1983, comes a special collaboration model celebrating the 20th anniversary of ONE OK ROCK, one of Japan’s most iconic rock bands.

The base model is the GM2100, featuring an octagonal metal bezel. A sleek silver bezel paired with a matte white semi-transparent band creates a cool, unified aesthetic. A black dial provides a sharp contrast to silver-finished hour markers, enhancing its refined look.

The dial is adorned with a cherry blossom motif in a delicate gradient finish, symbolizing the elegance and tradition of Japanese culture. The subdial at 9 o’clock features a hand inspired by a katana (Japanese sword), further emphasizing this model’s connection to Japanese heritage. Roman numerals on the bezel add a timeless, classic watchmaking touch.

The metal band ring is engraved with a design inspired by bassist Ryota’s tattoo, while the case back features a special logo designed by Swedish artist Emil, a close friend of the band.

This exclusive collaboration model comes in custom packaging designed by Emil, meticulously crafted to reflect the unique world of ONE OK ROCK. Every detail of this watch has been carefully considered, making it a truly special anniversary timepiece.
