Casio unveils new G-Shock GM-6900XG in Japan with translucent strap and special backlight

Casio has unveiled the G-Shock GM-6900XG-8, its latest collaboration with seven-member Japanese music group XG. The new watch builds on the familiar 6900 series, introducing several cosmetic changes inspired by the group’s music and identity.

The GM-6900XG-8 features a silver-colored stainless steel bezel paired with a translucent resin strap. The latter 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 features include an X-shaped front button that activates the watch’s backlight. When illuminated, the display reveals a howling wolf, a reference to XG’s fanbase, known as Alphaz. The case back features the Japanese character 緒, which represents the bond between the group’s members and their fans. Casio has also included special packaging featuring seven wolves, one for each member.

As for specifications, the GM-6900XG-8 measures 53.9 × 49.7 × 18.6 mm and weighs 107 grams. It offers shock resistance, 200-meter water resistance and 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 one introduced the GM-S5600XG with rainbow-finished glass and the pink GMA-S110XG. Both watches subsequently arrived in Japan in June 2026.

According to Casio’s Japanese product listing, the GM-6900XG-8JR is scheduled for release in November 2026. However, the manufacturer has not yet confirmed an exact release date or official pricing. International availability details are also pending.
