What Is A Tourbillon?
A Tourbillon (meaning “whirlwind” in French) is a device invented by in 1795 Abraham Louis Breguet to counteract the effects of gravity in the accuracy of clocks and watches. The tourbillon was originally designed to eliminate errors of rate in pocket watches, which were kept in vertical positions for long periods of time.
How Does A Tourbillon Work?
When a watch is in the vertical position, gravity either accelerates or slows the balance and escapement mechanism that regulates the speed of rotation of the wheels. A tourbillon is comprised of a mobile carriage or cage containing the regulating mechanism (balance wheel with hairspring) and the lever escapement, with the balance in the center, and this mechanism rotates the wheels. The escape pinion turns about the fixed fourth wheel. By mounting the escapement in a rotating frame, all errors were reproduced and thereby cancelled the effect of gravity when the escapement is rotated 180°. The frame makes one revolution per minute, thus annulling errors of rate in the vertical position. The rotation of the whole device around the axis of the frame suppresses the effects of friction or other effects caused by unbalanced components and gravity.
Considered as one of the most complex of watch complications, tourbillons are prized for their engineering and design principles. Building a tourbillon is viewed as a testament to a watchmaker’s skill and the sheer complexity and achievement of such miniature handmade mechanisms makes the movement one of the most valued complications.
