Friction, Lubrication and the Lubricants in Horology

This work offers a clear guide to the often‑overlooked art of keeping watches and clocks running smoothly. It begins by explaining where horological oils come from, describing traditional sources such as porpoise‑jaw and black‑fish‑melon oils, and the modern refining techniques that make them reliable lubricants. The author then connects those basics to the physical principles of friction, showing how a proper understanding of slip and wear can prevent the premature failure of even the finest timepieces.

In later sections the book surveys the properties of various lubricants, comparing viscosity, stability, and suitability for different escapements. Practical advice is woven throughout, drawing on the experience of manufacturers and repairers who have tested these substances in real‑world conditions. Readers will come away with both the scientific background and the hands‑on tips needed to choose and apply the right oil, ensuring their watches keep accurate time for years to come.
