XG and G-SHOCK hide fandom details inside a new watch
XG and Casio turn a G-SHOCK watch into a fan collectible with a tattoo-style band, wolf backlight and hidden references to the group.
A silver metal bezel meets a translucent strap printed like a wrist tattoo. Press the X-marked button, and a howling wolf appears in the backlight. These are the details behind Casio's second G-SHOCK collaboration with seven-member group XG.
Announced November 12, the GM-6900XG takes the familiar 6900 watch shape and gives it design cues tied to the group's identity and its ALPHAZ fandom. The result is a wearable collaboration that makes fan references part of the product itself rather than relying only on a celebrity campaign photograph.
In this article: The tattoo-inspired watch design, its hidden fan references, the Japan release and what marketers can learn from product-led fandom collaborations.
A watch band designed to look like a tattoo
Casio calls the design concept “TIME, INKED ON YOU.” The GM-6900XG combines a silvery metal bezel with a translucent resin band carrying “Xtraordinary Genes,” XG's full name, in a bold, multi-angle graphic. Casio says the metal represents the strength built through the group's journey, while the transparent material suggests future possibility.
The watch uses the 6900 series' recognizable three circular dial indicators. Rather than redesigning its entire silhouette, Casio makes the collaboration visible through its material contrast, printed strap and small custom details. The group's creative ideas informed the watch, according to Casio.
A wolf appears when the backlight turns on
The front button bears an X. Activating the light reveals a silhouette of a howling wolf, the symbol of XG's fan community, ALPHAZ. This transforms an ordinary watch interaction into a small moment of fandom recognition.

Casio also engraves the Japanese character 緒 on the case back, drawing on hesonoo, the call the members use during their pre-performance huddle. The packaging extends the idea with a graphic of seven wolves, one for each member.

The second watch deepens an existing partnership
XG has served as a G-SHOCK global ambassador since July 2025. The GM-6900XG is the second collaboration timepiece from the partnership, moving beyond ambassador imagery into a product whose surfaces and functions carry specific references for fans.
Casio's Japanese announcement sets the Japan release for November 27, 2026, at ¥39,600 including tax. Availability and timing vary by market: Casio's Singapore product page lists the watch as coming in December at S$399. These are market-specific listings, not a confirmed single global launch date.
What marketers can learn from XG's G-SHOCK watch
The design illustrates a useful distinction between celebrity merchandise and a deeper product collaboration. The band graphic is immediately recognizable, but the wolf backlight, engraved character and packaging reward fans who know the group's rituals and symbols. Each detail gives the audience a different way to connect the physical object with the artist.
For marketers, the replicable principle is to build authentic community references into a product's existing functions, materials and unboxing experience. Casio has not disclosed sales or conversion results for this new model, so its commercial impact remains to be seen. The design itself, however, shows how a brand can translate fandom into tangible product features.
