G-SHOCK and XG's Second Collaboration Writes 'Xtraordinary Genes' Across a Clear Band, Out November 27

Casio will release the GM-6900XG, its second G-SHOCK collaboration with the seven-member group XG, after the GM-S5600XG and GMA-S110XG it announced on May 28, on Friday, November 27, for ¥39,600 including tax, according to the company's Japanese release on November 12. XG, which is JURIN, CHISA, HINATA, HARVEY, JURIA, MAYA and COCONA, has been a G-SHOCK global ambassador since July 2025, Casio says.

The watch is built on G-SHOCK's 6900 series, the one with three round indicators across the dial, and pairs a silver metal bezel with a clear, skeleton band. Casio calls the creative concept "TIME, INKED ON YOU". The band carries the group's full name, Xtraordinary Genes, as a graphic meant to look like a tattoo on the wrist.

Built for ALPHAZ

Most of the details are written for XG's fans, known as ALPHAZ. The front button carries an X mark, and pressing it lights the display with the silhouette of a howling wolf, the ALPHAZ symbol. The caseback is engraved with 緒, a character Casio says comes from "HESONOO", the call the members use when they huddle before a show. The special box has seven wolves printed on its base, one for each member.

The watch lands in a busy year for the group. Casio's release notes that XG put out its first full album, THE CORE, on January 23, 2026, and has been on its second world tour since February. Its merch has also been turning up beside fashion this month: XG has its own long-sleeve tee in Spotify's ZOZOVILLA collection for its Tokyo show in December.

Our read

This is a fan object before it is a watch release. The 6900 shape is one of G-SHOCK's most familiar, and nearly everything that sets this one apart, the wolf in the backlight, the character from their huddle call on the back, the seven wolves under the box, is a reference only ALPHAZ will read. That's a different brief from a streetwear collab, where the partner's graphics have to sell to people who don't know the backstory. What's still unconfirmed is whether it travels: Casio's release is a Japanese one with a yen price, and Notebookcheck reports that international availability hasn't been announced.
