Antique Watch Restoration Vol. 1 by Archie B. Perkins. He also wrote The Modern Watchmakers Lathe and How To Use It.
There are supposed to be more volumes published later, i think up to 3, but even this first volume is filled with useful restoration knowledge, pretty much everything is explained and detailed in a practical manner, and any theoretical information is really only there to support the practical information and guides. It's the only book that i've come across that gives a detailed explanation of how to use the Ingold Fraise, it even includes some theoretical data for how to select a properly sized cutter.
