The balance wheel is an important component of the movement, determines its accuracy and characteristics, but it is usually ranked escape escape (Escapement) and gossamer (Balance Spring) after. The exact function of the balance wheel is not well known, it is actually an inertia flywheel for storing and returning energy. The energy is provided by the mainspring, through the escapement, to the end of the balance wheel connected to the hairspring. Gossamer "breathing" (Zhang), two components together with the oscillation. Ideally, the movement frequency should be constant, on this basis, calculate the seconds, hours and higher units.
