Some collabs slap a logo on the dial and call it a day. This one prints the group’s name down a clear band like a tattoo, then hides a wolf inside the backlight.
It’s the GM-6900XG, the second G-Shock built with XG, the seven-member group behind X-POP. Casio built the whole design around one idea, TIME, INKED ON YOU, and the details keep going from there. Every surface carries a reference, if you know where to look.
It helps that the base watch is the 6900. Casio calls that shape the starting point for its culture-inspired designs, and the triple-graph dial reads instantly at a glance. It is the canvas Casio reaches for when a collab needs room.

The band does the talking
Start with the band, because it’s the first thing anyone notices. It’s translucent resin, and the group’s full name, Xtraordinary Genes, runs across it in a flowing script.
Yes, the band is the headline act here.
Casio prints the lettering at several angles, so it wraps and twists like ink on skin. In the group’s interview, CHISA says the members talked through whether the name should fit neatly inside the band.
They picked the version that spills past the edges. Staying inside the lines was never really their thing, and the watch comes out better for it.
The case goes the other direction. A silver metal bezel rings the triple-graph dial, bright against the band.
Casio mapped a meaning onto each material, too. The metal stands for the strength of time already lived, and the clear band points at a future still changing shape.
Press the X, get a wolf
The front button carries a big X, and pressing it lights up more than the time. The LED backlight throws a howling wolf silhouette across the display. That X is the light button, so the wolf shows up every time the display glows.
The wolf stands for ALPHAZ, XG’s fandom. Every late-night time check turns into a tiny fan signal.
It’s a small detail. It absolutely lands.
Flip the watch over and there’s one more engraving to find. The case back carries the character 緒, the last character of hesonoo, the call the members shout in their pre-show huddle.
Even the box joins in, hiding seven wolves on the bottom of the packaging, one for each member.
Round one moved fast
This is XG’s second run at a G-Shock, and the first one explains the energy. The GM-S5600XG and GMA-S110XG landed in June, and orders flooded Casio’s online store the moment reservations opened.
XG has been a G-Shock global ambassador since July 2025, so this partnership is past the trial stage. Seven members, JURIN, CHISA, HINATA, HARVEY, JURIA, MAYA and COCONA, all had a hand in this design.
If the group is new to you, the short version is simple. XG built a genre of their own, closed the Sahara stage at Coachella, and played to about 50,000 people at Tokyo Dome. Their second mini album, AWE, also cracked the Billboard 200, a first for the group. ALPHAZ, the fandom, counts in the millions across the group’s social accounts.
The watch under the graphics
Under the fan service sits a regular 6900-series G-Shock, which is a good place to start. The case is shock resistant with water resistance rated to 200 meters, so it shrugs off rain, sinks and swim days.
The three round graphs above the display are the 6900 signature. They stay front and center here, framed by that silver ring, and they give the dial its busy, technical face.
The everyday kit is all here. There’s a 1/100-second stopwatch, a countdown timer, a multi-function alarm and a flash alert that blinks along with the alarm.

Watch the members talk it through
Casio filmed the visual shoot and sat the members down to talk through the design, band debate included. The full behind-the-scenes interview is worth the watch if you want the story from the seven of them directly.
Price and dates, with one big asterisk
Japan gets it first. The GM-6900XG goes on sale there on November 27 at $249, and Casio’s Singapore store already lists a December release. Casio’s international page tags it a November 2026 release.
For US fans, Casio hasn’t set a date or a price yet. Collabs like this one tend to travel, but nothing is confirmed, so hold off on resale listings until Casio says otherwise. When a US date does land, it’ll show up on Casio’s US store first.
