A normal tourbillon has no effect in horizontal positions, since the horizontal balance is not affected by gravity as it turns. A tourbillon has no effect on the change in rate that accompanies a change in attitude from dial horizontal dial up or down to dial vertical pendant up, down, left or right. The change in rate between horizontal and vertical is much greater than rate changes between different vertical positions. Breguet designed the tourbillon for pocket watches that are kept in a vertical position in the waistcoat pocket, and can be maintained in this vertical position overnight by hanging on a suitable stand.
In this attitude a tourbillon is effective. However, the attitude of a wristwatch changes frequently from vertical to horizontal depending on the wearer's hand movement. The effect of a tourbillon is small compared to the change in rate resulting from changes from vertical to horizontal, and vice versa.
Inclined tourbillons such as those made by Greubel Forsey are an improvement in this regard. Mechanical watches are now purchased by those who value craftsmanship and aesthetics over very accurate timing. Most tourbillons use standard Swiss lever escapements , but some have a detent escapement. The tourbillon is considered to be one of the most challenging of watch mechanisms to make [3] [4] although technically not a complication itself and is valued for its engineering and design principles.
The first production tourbillon mechanism was produced by Breguet for Napoleon in one of his carriage clocks travel clocks of the time were of considerable weight, typically weighing almost pounds. Anthony Randall invented the double-axis tourbillon in January and subsequently patented it. In Anthony Randall made a double-axis tourbillon in a carriage clock, which was located in the now closed Time Museum in Rockford, Illinois, US, and was included in their Catalogue of Chronometers.
In , inspired by this invention, the young German watchmaker Thomas Prescher developed for the Thomas Prescher Haute Horlogerie the first flying double-axis tourbillon in a pocket watch and, in , the first flying double-axis tourbillon with constant force in the carriage in a wristwatch. Shown at the Baselworld and in Basel, Switzerland. A characteristic of this tourbillon is that it turns around two axes, both of which rotate once per minute. The whole tourbillon is powered by a special constant-force mechanism, called a remontoire.
Thereby even force is always supplied to the oscillation regulating system of the double-axis tourbillon. The device incorporates a modified system after a design by Henri Jeanneret.

A spherical differential connects the four rotating carriages, distributing torque between two wheels rotating at different speeds. In , Thomas Prescher developed the first triple-axis tourbillon for the Thomas Prescher Haute Horlogerie [10] with constant force in the carriage in a wristwatch.
Presented at the Baselworld in Basel, Switzerland, in a set of three watches including a single-axis, a double-axis and a triple-axis tourbillon. The world's unique tri-axial tourbillon movement for wristwatch with traditional jewel bearings only was invented by the independent watchmaker Aaron Becsei, from Bexei Watches, in The Primus wristwatch was presented at the Baselworld in Basel, Switzerland.
This is a unique solution at this size and level of complication. Rather than being supported by a bridge, or cock, at both the top and bottom, the flying tourbillon is cantilevered, being only supported from one side.
