For some 220 years, the tourbillon was one of the most fascinating horological devices invented by Abraham-Louis Breguet.

Patented on June 26, 1801, the invention counteracted Earth’s gravity that affected a movement’s regularity. The effect of gravity caused variations in the rate, which was a problem as timepieces were mainly worn vertically along the body at that time.
To improve the accuracy, Breguet’s solution was to install the entire escapement inside a mobile carriage performing one complete rotation per minute. Errors were thus regularly reproduced…
