Considered one of the most prestigious complications in horology, the tourbillon was invented by no other than the famous watchmaker Abraham-Louis Breguet. He patented his invention on June 26th, 1801. Other makers and brands have since adapted the ingenious mechanism which was developed to make watches more accurate. By mounting the escapement and balance wheel in a rotating cage, the effects of gravity when keeping the watch in a certain position are negated. In other words, the tourbillon averages out errors from different positioning of the watch.
