Balance

That part of a watch or chronometer which regulates the action and determines the regularity of beat or strike.
The Balance Wheel usually circular, oscillating about its axis of rotation. The hairspring coupled to it makes it swing to and fro, dividing time into exactly equal parts. Each of the to-and-fro movements of the balance ("tick-tack") is called an "oscillation". One oscillation is composed of two vibrations.
