Only tangentially related, but if you ever get the chance to check out the Patek Philippe Museum in Geneva you should do so. I'm not really a watch geek so before going there I was kind of "meh", but that place is incredible.

They have thousands of timepieces, some dating back to 1530. To see what people have been able to accomplish with nothing but springs and tiny gears is nothing short of mind-blowing. As a technologist it's pretty humbling, considering all the advantages we have today and yet ancient watchmakers could do this work literally with nothing but hand tools.
