Other Notes: In horology, a tourbillon (or "whirlwind" in French) 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 trys to counter the effects of gravity by mounting the escapement and balance wheel of the watch movement in a rotating cage, to negate the effect of gravity when the timepiece (and thus the escapement) is left in a certain position. Originally an attempt to improve accuracy in pocket watches, tourbillons are still included in some expensive modern watches as a novelty and demonstration of the pinnacle of watchmaking virtuosity. The tourbillon cage and balance wheel are usually exposed on the watch's face to show off the intricate mechanism.
