Funny thing about mechanical watches, the technology hasn't changed in 150 years. The technology around tooling has changed substantially, which in turn allows us to produce more accurate and cheaper watch components and movements, but we're still producing the same old watch design that we (Americans) stole from the Swiss and started mass-production of.
The book I used in school was "Theorie de l'horologie" [1], which is a fairly modern book. I supplemented this with "The Bulova Watch Repair Training Manual" [2] and "Practical Benchwork for Horologists" [3]. I would argue that the most useful book for practice was "Practical Benchwork", which was originally released in 1938, it's latest edition being from 1988.
