Introduction
The document introduces the Flyfix assembly kit designed for flying tourbillon and carrousel mechanisms in watches. These mechanisms compensate for gravitational effects on the movement rate by rotating the regulating organ mechanism within a cage.

Specifications
- Meticulous finish of raceways.
- Lubricant-free operation using ceramic balls.
- Reduction of operational play.

Design and Aesthetics
The flying tourbillon is designed to enhance aesthetic appeal by making the tourbillon cage appear to 'fly' over the bridges, creating a weightless effect above the dial. This design choice, while visually appealing, presents technical challenges.

Technical Challenges and Solutions
To achieve the desired aesthetic without compromising functionality, the tourbillon cage is retained and guided by a ball bearing. The outer ring of the bearing is pressed into a bridge, requiring precise manufacturing to avoid blocking rotation or incorrect positioning.

Innovative Assembly Solution
MPS offers an innovative assembly solution that eliminates mechanical stress and prevents deterioration during assembly and disassembly. The bearing's outer ring is axially held on the bridge using a nut, ensuring proper fixation and centering. A torque wrench is used to tighten the nut, ensuring the assembly's strength.

Conclusion
The Flyfix assembly kit provides a meticulous and innovative solution for assembling flying tourbillon and carrousel mechanisms, balancing aesthetic appeal with technical precision.
