Something that really blew my mind is how far mechanical accuracy can be taken when money is no object. It's said that George Daniels could make mechanical watches that were more accurate than the quartz watches of his day[1], 0.4 seconds per year. Of course that doesn't really matter if the thing is a priceless work of art that no one can afford to wear day to day but it's still really interesting to know how he did it. Quartz watches' real advantage is just their accuracy but that they are accurate and cheap to make. There's something rather wonderful about a practically disposable Casio like a Bic Biro. 1. https://www.sothebys.com/en/articles/george-daniels-the-worlds-greatest-watchmaker https://www.sothebys.com/en/articles/george-daniels-the-worl... 2. https://www.danielslondon.com/daniels-watches/the-space-traveller/ https://www.danielslondon.com/daniels-watches/the-space-trav...
