Modern Style Technical Diagrams of Vintage Watches

I'm sometimes asked if there are things like exploded diagrams of vintage watches. Usually there are not. There's reasons for that.

I remember once when I did not know anything at all about watches, and I mean nothing, my grandfather was showing me how things are disassembled and reassembled. I asked the pretty basic question of how he remembered where everything goes. He said, "well it only goes one way." Which is almost always true. But it wasn't until years later that I understood what he was saying, after reading some of the works of my grandfather's teacher, who was a well known watchmaker in his day. He advised that students should study and completely understand how something works before doing anything. What I realized is that the best way to know what's going on with all those parts is to fully understand how the mechanism works. Then the question doesn't even arise. 

It only goes one way.
