Beat rate. Beat error is adjusted differently.
Apr 15, 2024,08:03 AM
While those pins allow the adjustment of the active hairspring length (slow/fast), the beat error is adjusted by setting the angular position of the balance wheel compared to the lever. The roller jewel that is part of the balance wheel should be aligned with the fork from the lever and the lever in the middle of the banking pins. This angular position can be set using different means. Most of the time, you have to twist the hairspring collet but some watches offer fine adjustments
