Following on from that post about watchmakers, here are a couple of videos explaining how mechanical and quartz watches work. In this opaque and bewildering hi-tech world of ours, it’s refreshing to find something complex yet still understandable.
First, this 1940s explainer from Hamilton. (I love the narrator’s accent!) Ironically, the pacing for this short documentary is a little slow by today’s standards, but I found that quite helpful.
How a watch works (1949)
A simple demonstration of the basic design and operation of a watch, including stop-motion animation showing a watch being assembled from many parts.
Science YouTuber Steve Mould brings us up-to-date with this look at quartz watches. I didn’t realise how similar they are to mechanical watches, in a way.

Quartz watches have a tiny crystal tuning fork inside that vibrates at 2^15 Hz and there’s a really clever reason for that. This video also talks a bit about how mechanical watches work.
