A few months back I stumbled upon a YouTube video of a watch maker servicing a mechanical watch. This started a mild obsession with watch making and I've been watching these videos ever since. For anyone interested, here's an awesome video [1] of a guy putting together a watch and explaining how all 60 parts of a typical mechanical watch work together (by the way the tools he uses are as cool as the movements themselves). It's surprisingly easy to follow for a noobie.
