Friction, Lubrication and the Lubricants in Horology

This work opens a practical window onto a subject that many watchmakers overlook: the science of friction and the oils that keep delicate mechanisms moving smoothly. By combining clear explanations of elementary physics with the hard‑won experience of leading horological manufacturers, it shows how a simple lapse in lubrication can turn a fine timepiece into an unreliable one. Readers are guided through the reasons why proper oil selection matters as much as gear design, and how even meticulous cleaning cannot compensate for ignorance of the underlying principles.

The book then surveys the origins and refinement methods of the oils most suited to horology, from traditional animal‑derived lubricants to newer preparations. It explains how different viscosities and chemical properties affect wear, timing, and long‑term stability, and offers practical advice on choosing and applying the right lubricant for various escapements. Throughout, the author weaves together historical insights, experimental observations, and industry data to give craftsmen a concise, reliable reference for keeping their watches ticking accurately.
