Mastering the art of precision timekeeping — a practical, proven guide to adjusting watches and chronometers for accurate, reliable performance.
This book explains the core principles that govern the motion of the balance and balance spring, and shows how to apply them to correct rate variations caused by isochronism, temperature, and position. It combines clear theory with hands-on techniques, including chapters on making a balance arbor, cleaning a watch, and remedying current defects in the lever escapement. The focus is on practical methods you can use at the bench to achieve consistent results.
- How to analyze and adjust isochronism and terminal curves for better rate stability
- Techniques for selecting, testing, and centering balance springs and mainsprings
- Step-by-step guidance for adjusting escapements, pallets, and fork action
- Hands-on procedures for timing, temperature compensation, and isochronism before temperature adjustments
Ideal for serious watchmakers and repairers seeking grounded, workmanlike methods that deliver real improvements in performance.
