Casio Unveils G-Shock GMC-2500 Series With Analog Design, 200m Water Resistance, and Shock Release Hand
Casio has introduced the new G-Shock GMC-2500 series, a fresh analog watch lineup inspired by one of the most important models in G-Shock history: the original DW-5000C from 1983. The new collection brings the classic square G-Shock spirit into a more refined analog format, mixing rugged durability with a dressier, metal-forward look.
The G-Shock GMC-2500 series arrives in five versions, split between stainless-steel bracelet models and lighter resin-band models. The stainless-steel GMC-2500D comes in two dial options: the black-dial GMC-2500D-1A and the blue-dial GMC-2500D-1A2. For those who prefer a lighter build, Casio is also offering three GMC-2500 models with a metal-clad case and textured bio-based resin band: the black GMC-2500-1A, the silver GMC-2500-1A8, and the gold-accented GMC-2500G-9A.
The series has already gained attention among watch fans thanks to its bold case shape and premium styling. Some enthusiasts have even nicknamed it the “CasioNaut” because of its visual resemblance to the Patek Philippe Nautilus. Still, Casio positions the GMC-2500 as a modern analog tribute to the first-ever G-Shock, rather than a luxury homage.
The design keeps the recognizable toughness of the original DW-5000C but softens the silhouette with smoother, more rounded case lines. Casio says the curved surfaces are designed to catch light differently depending on the angle, giving the watch a more dynamic look on the wrist. The dial remains clean and practical, with sharply defined indexes that make the time easy to read at a glance.
One of the standout features is Casio’s new Multi-Mission Date display. Positioned at 3 o’clock, the three-cell window normally shows the date, but it can also switch to display stopwatch minutes or setting information depending on the active mode. After the user sets the year, month, and day, the watch’s full auto-calendar takes over and remains programmed through 2099. That means owners will not need to manually correct the date for regular month changes or leap years.
At 9 o’clock, the GMC-2500 includes a small seconds hand with a “Shock Resist” marking at the tip. Casio has also added a practical power-saving option that allows users to stop the small seconds hand when it is not needed, then restart it later. This feature helps extend battery performance, with the CR1025 battery rated for around two years of use.
Unlike some of Casio’s higher-end full-metal G-Shock watches, the GMC-2500 series does not include Tough Solar charging or Bluetooth connectivity. Instead, the focus is on a traditional battery-powered analog experience with classic G-Shock durability.
Another interesting addition is the Shock Release Hand system. Casio says the minute hand is magnetically attached rather than fixed rigidly in place. This design helps the hand absorb impact during hard knocks or drops. After a strong shock, the hand may briefly shake or move out of position, but it is designed to return to the correct position within a few minutes. There is also a hand shift function, which moves the hands out of the way so the user can view the dial information more clearly.
All five G-Shock GMC-2500 models share the same case size of 46.7 × 43.8 × 12.9mm. They also feature mineral glass, 200-meter water resistance, and a stated accuracy of ±15 seconds per month. Other functions include a 1-second stopwatch that can measure up to 29 minutes and 59 seconds, plus an amber LED light with afterglow for improved visibility in low-light conditions.
The stainless-steel GMC-2500D models weigh 138g and use a one-push three-fold clasp. The bracelet is designed to fit wrists from 150mm to 205mm. The resin-band GMC-2500 models are much lighter at 68g and fit wrists from 145mm to 215mm. Depending on the color, the brass dials feature either a sunray or honed finish, with the date window color matched to the dial for a cleaner appearance.
In Japan, the GMC-2500-1A and GMC-2500-1A8 are priced at ¥37,400, which is approximately $238. The gold GMC-2500G-9A costs ¥39,600, or around $252. The stainless-steel GMC-2500D-1A and GMC-2500D-1A2 are priced at ¥49,500 each, or about $315.
The full Casio G-Shock GMC-2500 lineup is scheduled to launch in Japan in November 2026. Casio has not yet confirmed international pricing or release dates, but given the attention around the series, a wider rollout could attract strong interest from G-Shock collectors and everyday buyers looking for a rugged analog watch with a distinctive stainless-steel or resin-band design.
