Product Information

The purpose of this Practical Course in Horology is to present the fundamentals of horology, both in theory and practice.

Part I of the book deals with wheel work and gearing, which involve the work of calculating the number of teeth of missing wheels and pinions and in determining their proper diameters. Principles of escapement design and an analysis of the balance and spring are given considerable space.

Part II treats repair methods, in which the making of a balance staff and the adjustment of the escapement are given more than the usual space allotted to these subjects.

Part III is concerned with the adjustments to position, isochronism, and temperature, factors that may be called the finishing touches of the horological profession.

Originally published in the 1940s, this book is a goldmine for those who want to be a capable and well-equipped horologist.
