Made in Glashütte: 6.2. Adjusting the end of the balance spring

The last, curved part of the balance spring is known as the end curve. In the past, there was even an inner end curve. The end curve is used to attach it to the stud holder, and thus to the balance cock. In addition, the end curve is often used to quickly adjust the pace of the watch, because the frequency—which is the oscillation of the balance wheel—can be influenced by changing the effective length of the balance spring. To ensure that this happens reliably and in even steps, the end curve must have a perfect radius to the center point. This requires a keen eye, a steady hand, and a great deal of experience. nomos-glashuette.com #nomos #nomosglashuette #madeinglashuette
