George Daniels' book, Watchmaking, is the seminal work for watchmaking. David Penney and the author both contributed to the illustrations and they are some of the most beautifully detailed drawings of watch works I have ever seen. The book is available through any site listed if you use a search engine to find an on-line store. There is a big difference in price between the latest an early editions so be aware of that.
It is a beautiful book and I've had guests who know nothing about watches thumb through it for several minutes - ignoring me totally.
Hope this helps.
