the watch in a state of full chord plane

Watch the swing and swing-related indicators introduced by the watch movement inside a wheel and hairspring composed of resonator, the oscillation cycle it determines the stability of the watch's timekeeping accuracy. The shock is the balance wheel from side to side, and it is the swing swings, swing in the watch industry, also called amplitude.

 

In accordance with the physics definition, the amplitude of vibration objects are static equilibrium position deviated from the maximum displacement. Watch the swing is always changing, it's stability and size depends on many factors. The main access is dependent on the degree of tight winding plate, spring is the more full, the higher the swing. In addition, and the balance wheel shaft tenon friction is also related to the time when the position changes, the direction of gravity balance spring and balance wheel shaft tenon also followed changes in the friction conditions. For example, watches the plane and vertical plane when the swing changes are very obvious, than the facade plane swing is usually about 40 degrees lower.

 

Other factors that affect the swing there are many, such as: watch design, lubrication condition, the axial and radial clearance of gears, springs and so stationary torque output. We say watch the swing high, that is, people commonly known as "table walk attraction", but not the higher the better, because the balance wheel can not reach the maximum rotation of 340 degrees. If you swing too high, will cause the watch happened, "hit the pendulum," which is actually a balance wheel escapement disc pork on a skewer nail head hit the outside of a phenomenon, the watch will go fast time-varying, sound watch walking loss of normal rhythm of the voice, to something more urgent playing the "clip-clop" like.

 

Generally believed that the watch in a state of full chord plane, swing between 240 ~ 320 degrees is appropriate.
