Tourbillon Swiss watch master Louis · Baoji invented in 1795 a clock speed control device. French Tourbillon (also known as Trinidad and Tobago), a "whirlpool" meaning, is equipped with a "rotary escapement speed governing mechanism" mechanical watches, tourbillon agencies, is to correct the gravity caused by the clock mechanism error. Tourbillon watch represents the highest level in the mechanical watch manufacturing process, the entire escapement speed control agencies together and can rotate, with a constant speed of rotation, so that its gravity on the mechanical watch "escapement" Minimize the impact and improve travel time accuracy. Tourbillon device design itself is used for pocket watches, because the pocket watch vertically in the pocket, or hanging on the neck, the gravity will affect the balance wheel swing speed, resulting in errors. Tourbillon principle is basically the gossamer, fork lever and escapement system designed to operate on the same axis, tourbillon will continue to rotate in operation, in order to reduce the impact of gravity. However, with the rise of the watch in the 20th century, because the watch is not placed vertically for a long time, the function of the tourbillon device is not as big as the pocket watch, but the tourbillon device is extremely complicated. Moreover, due to the relatively high production cost and the process requirements, So Tourbillon has become synonymous with high-level watches. Ball-shaped tourbillon ball tourbillon shape similar to the ball, ball tourbillon not only visually more three-dimensional, to ensure that the travel time is also a great achievement. Ball Tourbillon first by the Jaeger-LeCoultre in Geneva in 2004 to launch. Floating Tourbillon In the 1920s Albert Helwing (head of technical department at Deutsche Uhrmacheerschule) in Germany invented the "flying tourbillon" (flying tourbillon), an unsupported tourbillon for Let the tourbillon as flat as possible. This free-standing frame was invented by Albert Helwing.
