Breguet: Tourbillon

Breguet Tourbillon is the invention of a speed control device. French Tourbillon "vortex" of Italy, Tourbillon is a combination of free translation and transliteration. Breguet Tourbillon inventions, correction to gravity caused by mechanical error.
Mechanical clock is able to behave in accordance with a certain rhythm to go, the escapement entirely precise control of the device. If the escapement high-speed action on their own accurate, the clock will then be substantially inaccurate. Escapement caused by speed control device movement is not accurate gravity is the culprit. Speed control device in place of the round is the use of the gossamer flexibility to complete the round before the campaign. As the gossamer always scroll to a certain direction, so when the place of position (up and down about the location) changes, the most by the effects of gravity will be corresponding changes. In addition, the axle in a different position by the gravity of the friction bearings will also force change. They have had a "poor location," the accuracy of error. For example, the watch will be placed in the plane, and the wear on the wrist when the regular swing, or have a fast or slow the difference.
