Casio G-Shock GM-6900XG-8 XG collaboration watch, Digi Mart USA News: Casio has unveiled the G-Shock GM-6900XG-8, its latest collaboration with the seven-member Japanese music group XG. The new watch builds on Casio’s familiar 6900 series and introduces several cosmetic changes inspired by the group’s music and identity, according to a publisher report from Notebookcheck.
The watch features a silver-colored stainless steel bezel paired with a translucent resin strap. The strap prominently displays the group’s full name, Xtraordinary Genes, using a multi-angle printing technique designed to resemble a tattoo.
Casio says the watch was developed around the creative concept of “Time, Inked on You.”
Other distinguishing details include an X-shaped front button that activates the backlight. When illuminated, the display reveals a howling wolf, a reference to XG’s fanbase, known as Alphaz.
The case back carries the Japanese character 緒, which represents the bond between the group’s members and their fans. Special packaging features seven wolves, one for each member.
In terms of specifications, the GM-6900XG-8 measures 53.9 × 49.7 × 18.6 mm and weighs 107 grams. It offers shock resistance and 200-meter water resistance, with an estimated five-year battery life using a CR2016 battery.
The underlying hardware is largely unchanged from other GM-6900 models.
This is Casio’s second collaboration with XG. The first introduced the GM-S5600XG with rainbow-finished glass and the pink GMA-S110XG, both of which arrived in Japan in June 2026.
According to Casio’s Japanese product listing, the GM-6900XG-8JR is scheduled for release in November 2026. Casio has not yet confirmed an exact release date or official pricing, and international availability details are also pending.
