Quick Summary
An overcoil is the outer coil of a Bréguet hairspring that is bent over the spring towards the center. An overcoiler is a worker who adjusts this overcoil to ensure it remains concentric with the balance staff as the spring winds and unwinds. This adjustment is crucial for the proper functioning of a watch's timekeeping mechanism.12
