Three new Casio G-Shock metal-bezel watches launch as Casio's own pages keep going missing

Casio's new G-Shock 2500 series also has a middle tier. The GMC-2500-1AJF and GMC-2500-1A8JF come in at ¥37,400 (about $234) and the gold-IP GMC-2500G-9AJF at ¥39,600 (about $248); these sit between the all-resin GAC-2500 at ¥20,900 and the steel-bracelet-fitted GMC-2500D at ¥49,500. All three are scheduled for November 2026 in Japan.

The construction is the reason for the gap. Case and bezel use resin, biomass plastic and stainless-steel, on a biomass-plastic resin band. That makes it weigh 68 g against 47 g for the fully resin GAC and 138 g for the steel GMC-2500D, so the range now spans nearly triple the weight across one design. Case dimensions are 46.7 x 43.8 x 12.9 mm, same as the full-metal pair.

Casio calls the date window a Multi-Mission Date, a three-digit rolling display that changes role depending on the function in use rather than only showing the date. It sits opposite a small-seconds subdial carrying a "Shock Resist" mark on the hand tip. The hour and minute hands are held magnetically rather than pinned, which Casio says lets them absorb impact, with the caveat that the minute hand can shift briefly before resettling.

The dials differ mainly by tier. Where the resin GAC uses a moulded plastic dial for depth, these get what Casio's Japanese copy calls a "BS dial", described as calmer and more restrained. The gold reference adds gold IP plating on the bezel alone.

Shared specifications run to 200 m water resistance, inorganic glass, Neobrite lume, an amber LED with afterglow, a 30-minute stopwatch, full auto calendar, ±15 seconds a month, a second-hand sleep function, and a battery rated at roughly two years.

Casio's Japanese product pages for the entire series have been intermittently unreachable since the listings appeared; the images have been sourced from @geesgshock on Instagram.
