The single axis tourbillon was invented by Abraham-Louis Breguet in 1801 to counteract the effects of gravity in pocket watches and improve their rates. Pocket watches were generally carried in the vest pocket in a vertical position, which was why Breguet’s invention only worked on pocket watches in this position. Once the watch was laid flat, on a table for instance with the dial up or down, the entire effect of the tourbillon was voided and no longer affected the rate.
