This invaluable, practical book is written by a watch repairer with over twenty years' experience. It is aimed principally at the novice mechanical watch repairer, although those with more experience will also find it most useful. Brimming with advice and useful tips, it provides step-by-step photographs with accompanying text and demonstrates how to maintain a mechanical watch, and how to identify problems and correct them. The author discusses the theory behind how a watch works and reveals how to take a watch apart and how to reassemble it without causing any damage. Each section of the book is related to a particular element within the watch, and the author clearly explains the function and design of each part.
