I didn’t know much about watches until my aunt died and I inherited an astonishingly beautiful pocketwatch from her. Looking online, I found it was made in Switzerland around 1800. It didn’t run, and when I opened the case I thought a small worm had gotten trapped inside. On closer inspection it wasn’t a worm but the tiniest chain I had ever seen, a perfect microscopic bicycle chain with links smaller than half a millimeter.
