"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."
