Oscillation is a term used to describe the back-and-forth movement of a watch’s balance wheel, which is a wheel-shaped device that helps regulate the timekeeping of a watch. Oscillation is powered by the energy of the mainspring and helps to keep the watch accurate. During oscillation, the balance wheel swings back and forth, with each swing generating a tiny electrical impulse that is used to keep the watch running. Oscillation is an important part of a watch’s movement and helps to ensure that the watch runs accurately.
