A tourbillon is a complex mechanism found in some high-end watches designed to improve accuracy. It consists of a rotating cage that holds the escapement and balance wheel, which helps counteract the effects of gravity on the watch's timekeeping. By continuously changing the position of these components, a tourbillon aims to minimize errors caused by the watch's orientation. Invented by the Swiss watchmaker Abraham-Louis Breguet in 1801, the tourbillon is often seen as a symbol of craftsmanship and luxury in horology. While modern advancements have reduced the need for tourbillons in everyday watches, they remain a sought-after feature for collectors and enthusiasts.
