Kieninger Exclusive Tourbillon Movement
Tourbillon comes from the French word "whirlwind" and it was developed as a valuable addition to horology around 1795 and patented by the French-Swiss watchmaker Abraham-Louis Breguet on June 26, 1801. Since then, a tourbillon became a recognizable part of the mechanics of some high-end clock and watch escapements. Tourbillon counters the effects of gravity by mounting the escapement and balance wheel in a rotating cage and thus negating the effect of gravity when the timepiece is stuck in a certain position. By continuously rotating the entire balance wheel/escapement assembly at a slow rate (typically about one revolution per minute), positional errors are averaged out and the timepiece achieves a higher precision. In addition to the functionality of tourbillon, it also has an immense design appeal.
