{wiki=Tourbillon}
A tourbillon is a sophisticated mechanism found in some watches, designed to enhance their accuracy, particularly in mechanical timepieces. Invented by the Swiss watchmaker Abraham-Louis Breguet in 1801, the tourbillon's primary purpose is to counteract the effects of gravity on the movement of the watch, which can cause variations in the timekeeping of a mechanical watch. The tourbillon works by mounting the escapement and the balance wheel in a rotating cage.
