The tourbillon (which is French for “whirlwind”) is an extra mechanism to the escapement of a watch. It aims to counter the effects of gravity by mounting the escapement and balance wheel in a rotating cage. This negates the effect of gravity when the timepiece, thus the escapement, is stuck in a certain position. Because of the continuous rotation of the entire balance wheel and escapement assembly positional errors are averaged out.
.
The tourbillon was developed around 1795 and patented by the French-Swiss watchmaker Abraham-Louis Breguet on June 26, 1801 as an attempt to improve accuracy.
.
The (mechanical) mechanisms of modern watches are so accurate that a tourbillon is not really necessary. Still, they can be found on (mostly expensive) watches, but more as a demonstration of watchmaking virtuosity.
