For the first time in more than two centuries of this invention – it is extremely necessary to achieve the accuracy of the time in a pocket watch and a stylish and fashionable sophistication today – His Majesty the tourbillon mechanism is subject to the stopwatch.

Actually, this is an obvious idea and worried engineers recently.

However, to solve a difficult problem was not immediately apparent, since it was necessary to find a way to instantly stop the balance wheel, enclosed in a cage of the tourbillon.

The traditional method of stopping the carriage that can not be achieved: the balance wheel braking is gradual, and if it stops, you will need to run it again.

You must keep it a potential energy for later start immediately.
