I might have missed it, but they did not include any of their "game" watches from the 1980s in the history, somehow! I spent many a happy hour on the submarine one (https://www.techrepublic.com/pictures/the-handheld-museum-a-...). The pyramid one was also popular.
>Casio should release one of their "game and watch" products again
Game and watch is a Nintendo product. They bring out remakes every now and then.
You are correct, they are probably just called Casio Game Watch like the Casio GC-7, GS-12 or GD-8.
I am always disappointed when I see products like their pac man watches that just have a print on it without any game related functionality. This has damaged the brand a lot already, and tbh, after many years being a hard core Casio fanboy I have moved on. But one more gaming watch...
