The GA-2100 is the G-Shock that got watch people interested in G-Shock again. Its octagonal bezel looked enough like an Audemars Piguet Royal Oak that collectors called it the “CasiOak”, and Casio has released it in dozens of colors and materials since 2019\. The new 2500 Series, which came out a week or so ago, I just hadn't been able to fit it in until now, is based on an older watch. It takes the DW-5000C, the square digital watch Kikuo Ibe designed to be nearly indestuctible, the first G-Shock from 1983, and turns it into a three-hand analog watch. The bezel corners are rounded, unlike the CasiOak, so this one has gotten a new Genta-inspired nickname: the “CasioNaut”, after the Patek Philippe Nautilus. The series has nine references in three variants: all resin, resin with a steel bezel, and a steel-bezel version with a matching bracelet. Prices range from $145 to $350.

The GAC-2500 is made entirely of bio-based resin. It is 44.5mm wide, 12.7mm thick and has a lug-to-lug of 46.7mm. The GMC-2500 puts a stainless steel bezel over the resin case, which makes it 43.8mm wide and 12.9mm thick. The GMC-2500G-9A has a gold ion-plated bezel. The GMC-2500D uses the same case on a bracelet. Every version has a mineral crystal and is water resistant to 200 meters, something you would expect from a G-Shock.

The GAC-2500 comes in black, white, yellow and dark green, with the strap matching the dial. The GMC-2500 has a brass dial in black (-1A) or silver (-1A8). The GMC-2500G-9A is gold-tone on the dial as well as the bezel, and the GMC-2500D has a black (-1A) or blue-gray (-1A2) dial. The window at 3 is a three-cell display Casio calls Multi-Mission Date. It shows the date, the stopwatch’s elapsed minutes or setting information, depending on the mode. Once you’ve entered the year, month and day, the calendar needs no correction until 2099\. The small seconds at 9 can be paused with a function called Second Hand Sleep to save battery. There is also an LED light. The minute hand is held in place by magnets, and Casio calls it the Shock Release Hand. A hard impact can push the hand out of place, and it moves back to the correct time on its own shortly afterward.

Inside is Casio’s quartz module 5757 with a 30-minute stopwatch, powered by a CR1025 battery. Casio rates the battery at about two years, or about five if you use Second Hand Sleep. The GAC-2500 comes on a matching bio-based resin strap. The GMC-2500 and GMC-2500G-9A have a textured resin strap, and the GMC-2500D has a stainless steel bracelet.

The Casio G-Shock 2500 Series is priced at $145 for the GAC-2500, $280 for the GMC-2500, $300 for the GMC-2500G-9A and $350 for the GMC-2500D. It should be available worldwide now. See more [on the G-Shock website](https://gshock.casio.com/intl/products/analog/2500/?ref=itsabouttime.email).
