In the steady rhythm of product launches that a company like Casio keeps, a new G-Shock has appeared quietly in Japanese listings: the GM-6900XG-8, made with the seven-member group XG for a second time. The watch keeps the sturdy machinery of the long-running 6900 series and changes mostly its face and its skin, so that what is offered is less a new instrument than a new way of wearing one. Its release is pencilled in for November 2026 in Japan, though the price and the reach beyond that country remain unspoken, as is often the case when a maker lets a listing speak before it speaks itself.
Casio's G-Shock GM-6900XG-8 Arrives With Tattoo-Style Strap and Wolf Backlight for XG Fans
Time, Inked on You
Mark
So what actually is new here? It sounds like a lot of watch.
Mimi
Mostly the surface. The strap, the bezel, the backlight graphic. The 6900 base and its hardware are largely unchanged.
Mark
The strap is the headline, though.
Mimi
Yes. It's translucent resin with the group's full name, Xtraordinary Genes, printed in a way meant to look like a tattoo. Casio calls the concept Time, Inked on You.
Mark
And the wolf?
Mimi
The backlight shows a howling wolf, a reference to the fanbase, called Alphaz. The packaging has seven wolves, one per member.
Luke
Worth saying what's solid here. The design details and specs are what Casio has described. The release timing is only from a Japanese product listing.
Mark
So no firm date?
Luke
Right. November 2026 is the listing's schedule. No exact date, no price, nothing on international sales.
Mimi
The case back has the character 緒 too, for the bond between members and fans.
Luke
That meaning is Casio's framing. I'd treat it as intent, not something independently checked.
Mark
Anything else we can say about the first collaboration?
Mimi
It produced the GM-S5600XG and the pink GMA-S110XG, both in Japan in June 2026.
Der Puls
- A second collaboration with XG arrives in Japanese listings with little fanfare, leaving fans to read the details themselves.
- The translucent strap with tattoo-style printing and the wolf backlight give the watch a loud identity over unchanged hardware.
- Casio has named a November 2026 release in Japan, but has offered no price, no exact date, and no word on international sales.
- Buyers and collectors are left waiting on the official price and whether the watch will cross borders.

Casio has quietly added a new watch to its Japanese product listings: the G-Shock GM-6900XG-8, its second collaboration with the seven-member group XG. The watch rests on the long-running 6900 series, and its changes are almost entirely in the look.
The visible transformation begins with a silver stainless steel bezel and a translucent resin strap printed with the group's full name, Xtraordinary Genes, in a multi-angle style meant to resemble a tattoo. The design follows a concept Casio calls Time, Inked on You. Small details speak directly to fans: an X-shaped front button activates a backlight that shows a howling wolf, a nod to the group's fans, the Alphaz. The case back carries the character 緒, representing the bond between members and fans, and the packaging shows seven wolves.
Beneath the styling, the specifications are familiar, with the same dimensions, weight, shock and water resistance, and battery life found across the GM-6900 line.
The first XG collaboration, which included the GM-S5600XG and the pink GMA-S110XG, reached Japan in June 2026. If the November schedule holds, this model follows about five months later.
The timing comes from Casio's Japanese listing, which names the GM-6900XG-8JR for November 2026. Beyond that listing, Casio has confirmed nothing further. The price, the exact date, and any plans for sales outside Japan remain open questions.
Casio has put a new watch on its Japanese product listings: the G-Shock GM-6900XG-8, built with the seven-member Japanese music group XG. It is the second time the company has teamed up with the group, and it takes the long-running 6900 series as its base, changing the look far more than the machinery.
The visible changes start with a silver-colored stainless steel bezel and a translucent resin strap. Printed across the strap is the group's full name, Xtraordinary Genes, applied with a multi-angle printing technique meant to look like a tattoo. Casio built the design around a concept it calls Time, Inked on You.
The details lean heavily toward the fans. The front button is shaped like an X and triggers the backlight. When the display lights up, it shows a howling wolf, a nod to XG's fanbase, who are known as Alphaz. On the case back sits the Japanese character 緒, which stands for the bond between the group's members and their fans. The packaging carries seven wolves, one for each member of the group.
Under the styling, the specifications are familiar. The watch measures 53.9 × 49.7 × 18.6 mm and weighs 107 grams. It is shock resistant and water resistant to 200 meters, and its CR2016 battery is rated for roughly five years. The hardware is largely unchanged from other GM-6900 models, so the collaboration is mainly a matter of finish and graphics.
The first XG collaboration produced two watches: the GM-S5600XG, with rainbow-finished glass, and the pink GMA-S110XG. Both reached Japan in June 2026, which puts this new model roughly five months behind them if the November schedule holds.
That schedule comes from Casio's Japanese product listing, which names the GM-6900XG-8JR for release in November 2026. The listing is as far as the confirmation goes. Casio has not given an exact date or an official price, and it has not said whether or when the watch will be sold outside Japan.
For now, the things to watch are the price and the release date on the Japanese market, and whether Casio extends availability abroad, as it has not yet said it will.
