I went digging through some old folders out of curiosity and I still have things I wrote in middle school and high school. (Not code, although I was starting with HTML at the time but that's lost to Geocities.)
Anyway, a bit of an indirect answer to your question but I found a paper I worked on in November 2000 (when I was a junior in high school). The works cited is below. None of the links still work. It could have been completely plagiarized and no one would know!
To answer your question, I still have a functional watch from 14 years ago.
