Watch and Clock Escapements

This volume offers a thorough exploration of the three principal escapement systems that have driven watch and clock making for centuries: the lever, cylinder, and chronometer types. Combining historical overview with hands‑on technical guidance, it walks readers from the earliest crude concepts to the finely tuned mechanisms used in modern horology. The text is grounded in the classic serials of The Keystone, presenting a unified treatise that has long been trusted by the trade.

Readers will find step‑by‑step instructions for drafting escapements, complete with the modest set of tools a workshop needs—drawing board, T‑square, dividers, and a specially crafted degree arc. Detailed explanations of angular measurement and the construction of precision dividers empower even novice craftsmen to achieve accurate layouts. Illustrated with nearly two hundred original drawings, the book serves as both a practical manual and a visual reference for watchmakers, repairers, and anyone fascinated by the mechanics of timekeeping.
