A normal tourbillon is supported by bridges that obstruct a clear view into the tourbillon. A flying tourbillon is only supported by just one side so that the rotating of the triple-axis tourbillon can be seen much better. To enjoy the tourbillon in all its beauty, the triple-axis tourbillon mechanism is driven via two conical gears instead of the easier gear-to-gear solution. Thomas Prescher was the first and is still the only watchmaker to use this system.
