A while ago I helped my father clearing up the attic and in one box I found a watch that I wore as a kid. My mother bought it me in the early 1990's, but I can't recall the exact year. The watch was dead, but since it was in a box with other stuff, it wasn't covered with dust and stayed in a dry environment all those years. So was in good condition. I bought a new battery and put it in the watch, grabbed a leather strap and put that on.
It runs fine. Here are pictures:
This was probably my second or third watch. I used to have some kind of sport watch too, but couldn't find that one.
Feel free to share stories and pictures of watches from your childhood, if you have any left of course.
