Tourbillon

In horology, a tourbillon or tourbillion "whirlwind" is an addition to the mechanics of a watch escapement. Invented in 1795 by Swiss watchmaker Abraham-Louis Breguet, a tourbillon counters the effects of gravity by mounting the escapement and balance wheel in a rotating cage, ostensibly in order to negate the effect of gravity when the timepiece (and thus the escapement) is rotated. Originally an attempt to improve accuracy, tourbillons are still included in some expensive modern watches as a novelty and demonstration of watchmaking virtuosity. The mechanism is usually exposed on the watch's face to show it off.

attached is the Tourbillon of Patek Philippe Calibre 89. The 2nd Most expensive Watch, it was made in 1989.

Inspired by these genius clockmakers the young german watchmaker Thomas Prescher developed for the Thomas Prescher Haute Horlogerie in 2003 the first flying Double Axis Tourbillon in a pocketwatch and in 2004 the first flying Double Axis Tourbillon with constant force in the carriage in a wristwatch. Shown at the Baselworld 2003 and 2004 in Basel, Switzerland.

Nowadays, most of the top 10 best watch comes wit Tourbillon, besides PP, AP, VC, Jaeger, IWC,

Omega, GP, Blancpain... all comes with various kind of beautiful design and layout of Tourbillon being show on the Dial. Breget has also created its Double Tourbillon.

Also, there are many watches are made with "Similar" layout to resemble the "tourbillon" but when we look at it carefully, there are not Tourbillon., just a turning wheel carries the second hand ...
