(Breguet Classique Tourbillon 5357BA/12/9V6)

In horology, a tourbillon is an addition to the mechanics of a watch escapement. Developed around 1795 by the French-Swiss watchmaker Abraham-Louis Breguet from an earlier idea by the English chronometer maker John Arnold, a tourbillon aims to counter the effects of gravity by mounting the escapement and balance wheel in a rotating cage, to negate the effect of gravity when the timepiece (thus the escapement) is stuck in a certain position.

In an attempt to improve accuracy, tourbillons are included in some more expensive modern watches as a demonstration of watchmaking virtuosity. The mechanism is usually exposed on the watch's face to show it off.
