While the chronometric results obtained using a cylindrical spring are remarkable, the manufacture of these balance-springs proves extremely complex.
It is with this in mind that the company decided to take on a new challenge by developing a cylindrical hairspring.
A cylindrical hairspring is designed for highly exclusive watches, produced in small numbers, or even for unique pieces.
Invented in the 18th century by John Arnold, an English watchmaker, the cylindrical hairspring is reminiscent of an endless screw or a corkscrew.
It is thanks to the cylindrical hairspring, fitted with a Breguet curve attached at two points, that friction on the pivots is reduced and isochronism is improved.
It boasted a number of novelties for the brand, including a flying tourbillon, a futuristic balance design, and a cylindrical hairspring.
The cylindrical balance-spring with its two terminal curves beats with a concentricity impossible to achieve with a traditional balance-spring.

He enhanced the concept by inventing the Reverso Gyrotourbillon 2 regulated by a helical balance-spring.
The second version of the Gyrotourbillon is distinguished by an essential organ: the presence of a cylinder-shaped balance-spring with end curves.

The verticality of this balance-spring, meanwhile, led the technical department to design a three-armed tourbillon bridge.
The latter were able to grasp the opportunity represented by the spherical tourbillon and to present a cylindrical balance-spring nestling at the heart of a wristwatch.

Four years later, the Grande Maison in the Vallée de Joux unveiled the Reverso Gyrotourbillon, the first three-dimensional tourbillon to feature a cylindrical balance-spring.
In comparison, a cylindrical balance spring is wound around a vertical axis, with each turn positioned on top of the next, and with each one having the exact same distance from the centre.
