Gyrotourbillon

Partially verified

A specific form of multi-axial tourbillon with a spherical cage rotation.

Definition

A specific form of multi-axial tourbillon with a spherical cage rotation.

Historical origin

Introduced by Jaeger-LeCoultre in 2004, designed by Eric Coudray.

How it works

Uses two cages rotating at different speeds and angles, often with a spherical hairspring.

The motion resembles a gyroscope, ensuring the balance is never in one position for long.

Pocket watch context

None.

Wristwatch context

Exclusively a high-end wristwatch complication from Jaeger-LeCoultre.

Identification

  • Spherical cage motion
  • Often paired with a cylindrical or spherical hairspring

Servicing notes

Manufacturer service only.

General guidance only. Complicated mechanisms should be assessed and serviced by a qualified watchmaker or clockmaker specialist, not adjusted at home.
