The traditional escapement has larger error because the swing rule of a balance wheel in the escapement is influenced by the gravity, and the tourbillon escapement invented by Mr. George in the current year aims to counteract the error of the gravity on the machine parts in the clock escapement system through the rotation of the tourbillon frame. The structure of the tourbillon escapement is that the escapement of the clock core is placed in a frame, and the frame regularly rotates 360 degrees around the axle center of the balance wheel, so that the original escapement is fixed, and when the resting position of the watch changes, the escapement is unchanged, so that different stresses are applied to escapement parts to generate errors; when the escapement mechanism rotates by 360 degrees ceaselessly, the azimuth errors of the parts are integrated and mutually offset, so that the errors are reduced to the maximum extent.

However, the traditional tourbillon escapements require very high installation requirements, and therefore the mechanical watches with tourbillon escapements on the market are expensive.
