I have two pocket watches.
The one on the left is a cheap souvenir from Kennedy Space Center. The one on the right is a super nice watch that was a gift from my brother for being his best man.
They both need a battery. I’ve figured out how to pop the backs off of both of them, and I figured out how to get at the battery in the cheap guy but not quite on the nice guy. I don’t have batteries either. Also, I don’t have any actual need to get these kids up and running.
I’m going to do it though. Not today, but soon.
