Tourbillon

The complication that counteracts the effects

of gravity to improve the accuracy of watches.

An opening in the dial allows you to admire this

mechanism as it rotates.

The tourbillon compensates for running errors due to gravity by mounting the balance wheel in a rotating cage. Equipped with a tourbillon, your watch runs with greater accuracy.

The balance wheel, whose oscillations govern the accuracy of the watch, is sensitive to gravitational force. When in a vertical position, it is slowed down or accelerated by the gravitational attraction of the Earth, causing the watch to go faster or more slowly. In a timepiece with a tourbillon, the escapement and the sprung balance, the regulating organs of the watch, are mounted in a rotating carriage. Turning about its own axis once per minute, this assembly passes through all vertical positions in succession. In this way, the opposing effects of acceleration and deceleration cancel each other out.

Patented in 1801 par A.-L. Breguet, the tourbillon is one of the supreme achievements of the watchmaker’s art. Only a few craftsmen have the skill to construct it.

In 1989, Blancpain presented a flying tourbillon, which runs in a carriage restrained and guided by a tiny ball bearing. This system provides a completely unimpeded view of the tourbillon cage.

Blancpain is also the watchmaking brand that has succeeded in developing and selling the greatest number of models combining the tourbillon with other complications. For example, at the turn of the century, the Le Brassus Manufacture presented the world’s first combination of the Tourbillon and Chronograph complications, as well as the first Automatic Tourbillon with Perpetual Calendar and 8-day power reserve.
