The Casio 2500 Is an Homage I Can Get Behind
The Casio 2500 nods to the Nautilus, and I'm okay with that. My first-look rating: 89/120 bezel clicks. Final specs and USD pricing remain unconfirmed.

The Casio 2500 is obviously a take on the Patek Philippe Nautilus, and I'm totally okay with that. I think this is going to be an extremely popular release, and a full-metal version would look real sick.
I've become a big G-Shock fan. I have a G-Shock 5000, the recreation of the original, and that's the only one I own at the moment. There will be more coming. This looks like it could end up being one of them, although I wouldn't be surprised if it sells out before I even realize it's actually been released.
The Nautilus part is pretty obvious
The rounded case, broad shoulders and overall shape are where the comparison starts. The watch shown in the teaser has an analog dial and a date window, and people have already started calling this the “CasioNaut.” Gear Patrol uses that nickname in its coverage; Casio's own announcement just says “New G-SHOCK coming soon…”.
I don't think the inspiration is a secret, and it doesn't put this into that uncomfortable range of homage for me. G-Shock itself is so different from a Nautilus. This feels like what an homage should do: give a nod to something while really doing its own thing with it. I wouldn't be surprised if Casio kept exploring that idea with other popular watch designs, and I'm totally okay with it.
I wanted to cover it now because I think this one is going to get a lot of attention. I'm already expecting that getting hold of one could take a while.
The version I'd want
I'm still waiting for the final specifications, prices and lineup. My guess is that pricing could sit somewhere around the CasiOak family, with resin and some sort of metal options, but that's an expectation rather than a confirmed price or range.
I want to see whether we get G-Steel, full metal, or both. If a full-metal version happens, that's probably the one I'd end up wanting, even if I don't have the money for it. The shape in metal is what I'm particularly interested in.
For the chart, I'm using $350 USD as a research estimate for the metal-bracelet GMC-2500D, dated October 20, 2026. Notebookcheck's September 23 prerelease report puts that version at $350, matching G-Central's September 17 pricing report. This is an estimate based on those reports, and official US pricing and availability remain unconfirmed. The chart uses that metal-bracelet version rather than a starting price for the resin watch.
My first-look rating is 89 out of 120 bezel clicks, based on the announcement and images. I think this looks like a solid new release. It might take me a while to actually end up with one, but I wouldn't doubt that I do at some point.
