I got my first watch in Fifth grade: a used mechanical watch with spinning number wheels which didn’t last but a few weeks. it drifted hours in a day and soon I was in the habit of taking it apart (one of the number wheels was loose and I’d hook it back on to get a few more hours use out of it). Next I went through a series of calculator watches, progressing in junior high through several “data bank” versions, into which I painstakingly typed the phone numbers of everyone I knew.
