I love these things. In my country these things I believe got popular in the mid 90s, I was a child and we simply could not afford to get a calculator watch especially not for a "young player" like me. And a year ago I started thinking maybe I could afford it so started looking around and found that these things were/are not that cheap nor manufactured (at least the DataBank + calculator line) but I could not whitstand the temptation and I bought 1 used (actually I was lucky and managed to get one pretty cheap). And as you know how gateway drugs work I did not stop there
. I made myself buy a Commodore 64 (wanted soooo bad as a child, could not afford either) along with some other stuffs like a digital diary (in my country we calle them manager calculators). Here is a picture of my little meaningless collection if I may
Oh and BTW, Seiko was playing with things back in the days too
