This small guidebook, an unabridged reproduction of how it was originally published in 1948 (see the trend in publication dates among these top-tier watchmaking books?), provides an introduction for those interested in learning more about how manual watches work. D.W. Fletcher, an amateur watch-repairing enthusiast, starts with the very basics of operations how a watch works(see thumbnails for examples), then moves through the tools used for repair, disassembling and cleaning, and closes with a troubleshooting section.
It is a short book that is easy to read, and provides a good starting point, though a very small amount of knowledge to start will certainly be useful (as much as books say for the “novice”, they really mean for the novice watchmaker, though readers really should have some knowledge of the parts and operation to some degree).
As an aside, the price can’t be beat.
