The XG G-Shock is too much branding for my wrist
41/120 bezel clicks. A sourced first look at GM-6900 XG.

The translucent band covered in XG lettering is where this G-Shock loses me. I like plenty of G-Shocks, but this particular combination of a round triple-graph face, shiny metal bezel and graphic strap is much more than I would want on my wrist. The wolf in the backlight is a fun detail. It doesn't change the rest of the design for me. I'd give the GM-6900XG 41 out of 120 bezel clicks.
This is Casio's second XG collaboration. The official announcement is dated November 12 in Japan and entered the November 11 Detroit release window through its distribution timing. It isn't the earlier XG model. The exact execution here is GM-6900XG-8, with a silver-colored metal bezel and translucent resin band. I haven't worn or tested it.
The band is the main design decision
Casio puts the group's full name, Xtraordinary Genes, across the band in a stylized graphic. The idea is deliberately close to a tattoo around the wrist. I can see how that would appeal if the connection to XG and its ALPHAZ fans were the point of buying the watch. For my taste, the repeated graphic makes it harder to enjoy the shape underneath.
The metal bezel looks good by itself. I prefer it when my eye isn't also trying to sort out the lettering on the translucent material. The 6900's three round upper displays already make a fairly distinctive face, and adding the band treatment creates too many competing details for me.
There is an X on the front button, a howling-wolf silhouette in the light and an engraved character on the caseback. Casio explains the back engraving through the group's pre-show huddle. Those details make this a specific collaboration rather than a generic color change. They still don't make it a watch I would choose over a quieter G-Shock.
Large, practical hardware underneath
The official specifications put the case at 53.9 mm long, 49.7 mm wide and 18.6 mm thick, weighing 107 grams. That is substantial. G-Shock is one category where I can forgive more size, but I would need to like the appearance enough to want that much of it.
Casio lists shock resistance, 200-meter water resistance, mineral glass and a CR2016 battery rated for approximately five years. The usual useful tools are present: stopwatch, countdown timer, alarm, calendar and an LED backlight. Those are manufacturer specifications, not results from testing here.
The Japanese announcement gives ¥39,600 including tax and a November 27 release. A verified USD price and US on-sale timing are still unknown. I wouldn't import the Japanese date into a US availability claim. If I were shopping the 6900 range, I'd compare the exact case fit and plainer band options before paying extra attention to this collaboration's packaging.
