✔️ Understanding the motion of the balance and spring
✔️ The impact of the escapement on accuracy
✔️ Balance wheel amplitude and isochronism
✔️ The effects of positional changes on accuracy
✔️ Poise errors and their correction
✔️ Temperature compensation techniques
🔧 Part 2: Preparing the Oscillating System for Adjustment
✔️ Proper poising of the balance wheel
✔️ Effects of poise errors and how to correct them
✔️ Techniques for attaching and adjusting the balance spring
✔️ How to fine-tune the terminal curve of a Breguet spring
✔️ Understanding regulator indexes and curb pins
⚙️ Part 3: Practical Watch Adjustment Techniques
✔️ Factory vs. repairer adjustments – differences and challenges
✔️ Testing the balance amplitude for precision
✔️ How to document and track adjustments
✔️ Using a timing machine for fine-tuning performance
✔️ How to improve accuracy in different positions
✔️ Adjusting a wristwatch for different rates (dial up vs. dial down, pendant positions, etc.)
✔️ Special considerations for chronometers and high-precision watches
