One of the reasons I love mechanical watches is that I've never tried to fully understand them, and the idea that there's a purely mechanical thing, that does something seemingly so simple yet magically and reliably, gives me a sense of wonder and appreciation for engineering and art.
I'm really on the fence about whether or not I want to read this amazing looking article or just live on in ignorance :)
I think that link will only improve your appreciation for how magical a mechanical watch is. Especially when you consider people have been making them or a few hundred years.
You're in for a treat then! Bartosz has a bunch of other insanely well done explainers on his website, with easily inspectable JavaScript too. Some of my favourites are the watch, the engine and the GPS ones, though they're all fantastic.
