If you have several casios you might be interested in this toy. But I don't really know what I'd do with it...It turns out that I have more watches than I thought I did, I thought I had 9 but I actually have 12. The majority are Casios, with the non Casio ones being an Armitron Griffy, a Skmei 1585, and a Vostok Komandirskie.
