I have a couple of Oceanus brand watches that I got in Japan. They are fairly un-cheap.
However, in Japan, their G-Shock brand (kind of lower cost, in the US), can get even more expensive than Oceanus. Some of them look like Pip-Boys (Because this is HN, I need to mention that this is a deliberate exaggeration).
Oh yeah I never heard of chrono24. I'm not a watch guy at all :) I was just interested because I used to have casio watches when I was young. After which the mobile phones emerged and I stopped wearing a watch at all, until they started doing more interesting stuff (payments and notifications are what interests me mainly).
It's entirely possible that the more expensive "G-Shocks" were Mr G. I remember seeing wording about titanium cases, etc., but most of it was in Japanese, so the only thing that jumped out at me, were the price tags.
Not offhand. I got the watches in that big Akihabura store, about 20 years ago, and they had a shitton of G-Shocks, as well as Oceanus. I saw several 6-digit prices.
Many of the folks I worked with, could afford good watches, and wore G-Shocks. They were quite proud of them.
I suspect you’ll see them on the Japanese Casio site.
