The regulating assortment (balance wheel, balance spring, pallet fork, escape wheel) are housed in a rotating “tourbillon” cage which eliminates/reduces rate errors due to the earth’s gravitational forces for increased precision. A complex mechanism requiring the highest watchmaking skills: consists of a mobile carriage carrying all the parts of the escapement. It is a regulating device that corrects for the gravity-caused differences in runtime in a mechanical watch. Most tourbillons rotate one complete time every 60 seconds.
