Memories. I had first Casio sometime in 1980s at age 8 or so, and it was solar fueled. I put it under desk lamp which was probably 100W back then to charge it faster, I guess, and then the plastic deformed. Little I knew putting it into a refrigerator will not make it back to be nice and square. 8 year old. And there has been so many styles, every year to release new catalog and for so many region/countries there are different styles. I can imagine there is one person out there, a real boss-level-type dude, who has a basketball-size room with all brand new Casio watches, each one style, still unopened.
