Understanding Flying Tourbillon Technology
Before examining the AESOP 7021 specifically, it’s essential to understand the technical significance of the flying tourbillon complication and why it represents one of watchmaking’s most prestigious achievements.
Traditional vs Flying Tourbillon Architecture
Feature | Traditional Tourbillon | Flying Tourbillon (AESOP 7021) |
---|---|---|
Bridge Configuration | Upper and lower bridges support the cage | Single lower bridge, cage appears to “fly” |
Visual Impact | Partially obscured by upper bridge | Unobstructed 360-degree visibility |
Construction Complexity | More stable, easier to manufacture | Higher precision required, more challenging |
Aesthetic Appeal | Traditional, classic presentation | Modern, dramatic visual effect |

The Physics of Tourbillon Operation
The tourbillon mechanism was originally conceived by Abraham-Louis Breguet in 1795 to counteract the effects of gravity on pocket watch accuracy. While less functionally necessary in wristwatches due to natural wrist motion, the tourbillon remains one of watchmaking’s most captivating complications:
- Escapement Housing: The entire escapement and balance wheel assembly rotates within a cage
- Rotation Rate: Typically one complete revolution per minute
- Gravity Compensation: Theoretical averaging of positional errors through continuous rotation
- Visual Fascination: Mesmerizing mechanical ballet visible to the wearer
- Technical Demonstration: Showcase of manufacturing precision and assembly skill
