Here is a unique book. It describes the theories and processes of repairing and adjusting the modern watch in precise and meticulous detail: a thing which has never been done so completely before in the many books on the same subject. As a text book it is a revelation. Taking nothing for granted, except the ability to read and comprehend a simple description of mechanical processes, de Carle takes his reader through every stage and every operation of watch repairing ...and to deal with them thoroughly is quite a programme - it takes 300 pages containing 24 chapters, two appendices and 553 illustrations. The fine draughtsmanship and accurate technical detail of the illustrations set a new standard. Practical Watch Repairing can justifiably claim to be the best illustrated book on practical horology yet issued, and one of the best of its kind on any subject. The publication of the book marks the beginning of a new epoch in the study of the mechanics of horology.

The repair of clocks calls for a variety of skills and crafts, few of which can be 'picked up' by bench work alone. In the horological trade, it is technical practice that the 'prentice hand' is first tried out on clocks, before attempting repair work on watches. Clocks have the advantage of possessing sizeable and robust parts and of being easier to handle. But there the advantage for the repairer ends. The sizes, shapes, complications and even the nationalities of clocks appear to be without end. Every movement has detail difference and, naturally, the defects when due for repair, are as varied. In this book, the author has dealt with the usual faults likely to develop in each type of movement in general use; from the lordly grandfather to the humble alarm. All the tools and equipment are described and illustrated, together with the ways of using them. The craftsman's most important and valuable tools of all - his skilful fingers - are shown in use in the clearest manner. As is usual in N.A.G. Press textbooks, the drawings have been specially made from parts under working conditions. A glance through the book will show their usefulness and clarity. Over 400 line drawings are used throughout and the reader is left in no doubt of what he is asked to do in following the author's clearly written technical and practical instructions.

This book's contents include: general condition of the movement; cleaning and oiling; balance pivots; fitting a flat balance spring; fitting a breguet balance spring; positional timing; further considerations when fitting a spring and observing the point of attachment; general notes on springing and timing; other methods of positional adjustment; and, timing machines. "No writer can have added more volumes to the horological bookshelf than Donald de Carle, and his careful and detailed approach to the technical side of the craft has done a great deal to improve the standard of knowledge of a host of craftsmen, and has gained him readers in every part of the world. The many craftsmen who are already familiar with Mr de Carle's earlier work, Practical Watch Repairing, will note a great similarity in the attitude of mind behind both books, and, indeed, this latest volume is, to some extent, a companion and a follow-on from the previous book, for it carries the reader into what is, undoubtedly, the most exacting and skillful aspect of all work on watches."
