ONE OK ROCK x G-SHOCK GM-2100TTTR-8AJR [Release Date/Price/Where To Buy]
A perfect blend of rock energy and Japanese tradition.
In an exciting fusion of music and style, Japanese rock sensation ONE OK ROCK is marking their monumental 20th anniversary with a bold new venture: a collaboration with renowned watch brand G-SHOCK.
Directed by the band’s bassist, Ryota, the partnership brings a fresh edge to the classic GM-2100 model, infusing it with the band’s signature energy and aesthetic.
About the ONE OK ROCK x G-SHOCK GM-2100TTTR-8AJR


The design features a sleek silver bezel paired with a white matte skeleton band, creating a cool, unified look. The dial is elevated with a silver vapor-deposited index and a black base, giving it a sharp and refined impression.
Adding a touch of Japanese elegance, the watch incorporates a beautiful gradient “cherry blossom” motif scattered across the dial, while a “sword”-inspired design at the 9 o’clock position pays homage to traditional Japanese culture. The bezel is adorned with Roman numerals, blending timeless watch aesthetics with a fresh, modern twist that sets it apart from previous G-SHOCK designs.
Further personalizing the piece, the keeper ring is engraved with a recreation of Ryota’s tattoo script, and the case back proudly displays the ONE OK ROCK logo. Encased in a custom-designed package that mirrors the watch’s unique aesthetic, this collaboration is a meticulously crafted, special edition timepiece that fans and collectors alike will treasure.
