Hairsprings are delicate, coiled springs typically made from a thin strip of metal, such as alloyed steel or silicon, that are used in mechanical watches to regulate the movement of the balance wheel. The hairspring is a crucial component in maintaining the accuracy of a timepiece, as it controls the oscillation of the balance wheel, which in turn regulates the movement of the gears that drive the hands of the watch. The quality and craftsmanship of a hairspring can greatly impact the precision and reliability of a mechanical watch.
