ONE OK ROCK
Formed in 2005, ONE OK ROCK has captivated a new generation of fans with its powerful blend of emo and rock, combined with high-energy live performances. Since making its major debut in 2007, the band has actively toured Japan, performing at live houses and major summer music festivals. Over the years, they have played at prestigious venues such as Nippon Budokan, outdoor stadiums, and large-scale arenas, as well as completing dome tours across the country. Beyond Japan, ONE OK ROCK has established itself as a globally recognized band, signing with international record labels and successfully completing world tours across the United States, Europe, and Asia following album releases. The band has also performed as a special guest on Ed Sheeran’s Asia Tour and MUSE’s World Tour. In Japan, they successfully completed a six-dome tour in 2023. Marking their 20th anniversary in 2025, ONE OK ROCK is set to release a new album, DETOX, in February. Their milestone year will also feature an extensive tour, kicking off in April in South America, followed by a North American tour starting in June, and culminating in a stadium tour across Japan beginning in August.
FEATURES


This sleek, stylish take on the GM-2100 pairs a distinctive silvery metal octagonal bezel with a translucent band in matte white for a design that is hardcore cool.
Indexes with a silvery vapor deposition finish pop against the black dial for a bold, yet pulled-together look.
The design captures the elegance and tradition of Japanese culture, with a delicate gradation of cherry blossoms scattered across the dial and the indicator hand on the 9 o’clock inset dial evoking a katana sword.



The bezel’s Roman numerals are a classy throwback to traditional timepieces, while introducing a fresh look never seen before in a G-SHOCK design.
A reproduction of bassist Ryota’s well-known tattoo is engraved on the band loop. The case back is adorned with the ONE OK ROCK logo, designed by Swedish artist and longtime friend of the band, Emil.
The distinctive packaging, also designed by Emil, exemplifies the spirit of this special G-SHOCK, born from a remarkable collaboration and showcasing meticulous attention to every detail.
