Notes

What is a Tourbillon? A Tourbillon is a regulating mechanism in which the escape-ment of a movement is housed within a revolving carriage. It was developed in an effort to attain better precision. When a watch is in a vertical position, the force of gravity will speed the balance wheel as it moves in its downward (arc) direction and slow it as it moves upward, creating devia-tional errors in the timekeeping. By placing the balance and escapement in a carriage that revolves 360 degrees per minute, these errors become averaged and the timekeeping becomes constant and consequently adjustable. Created by Abraham Louis Breguet in 1795, the tourbillon is considered a difficult and complex achievement by any watch manufacture.
