So I have a few of his watches, he wasn't a watch enthusiast so they are nothing great, but none the less they are my late grandfathers timepieces
My favorite one is this Elgin from 1954, I made it work for modern times with a nato strap custom cut. It was missing the crown, and couldn't be wound. I got very lucky and found a very similar watch as a donor watch to get some parts off of it, I ended up replacing the whole stem, spring bars, and case back, which all had issues. I cleaned everything as best I could and adjusted the watch timing, runs pretty darn good for a watch that was neglected from the 50s.
