The tourbillon has been regarded as one of the most prestigious and complex watch complications, a symbol of high horology and mechanical mastery. Originally invented in 1801 by Abraham-Louis Breguet, the tourbillon was designed to improve timekeeping accuracy.
Despite its niche appeal, the tourbillon market is experiencing growth, driven by rising demand for ultra-luxury and limited-edition timepieces. A recent industry report from 2024 revealed that high-end collectors are willing to pay premium prices for unique tourbillon models, with some fetching millions at auctions.
Let's learn more about tourbillons in this article. Owning a tourbillon watch today is not just about accuracy but also about heritage, exclusivity, and innovation. Whether housed in a skeletonized movement, a sapphire case, or combined with other high complications, a tourbillon represents a commitment to the art of traditional watchmaking.
What is a Tourbillon Watch?
A tourbillon is a sophisticated watch complication designed to improve the accuracy of a mechanical timepiece by counteracting the effects of gravity.
In a traditional mechanical watch, gravity can affect the balance wheel’s oscillations, leading to small variations in timekeeping. The tourbillon addresses this by continuously rotating the entire escapement, thereby averaging out gravitational inconsistencies. While initially designed to improve timekeeping precision in pocket watches, modern wristwatches often incorporate tourbillons as a display of high-end craftsmanship rather than for strict accuracy improvements.
What Is the History of the Tourbillon Movement
Let's check out a bulleted history lesson about the tourbillon mechanism.
Early Development and Invention
- 1795 – Swiss-French watchmaker Abraham-Louis Breguet conceptualizes the tourbillon to improve timekeeping precision.
- June 26, 1801 – Breguet patents the tourbillon (Patent No. 157), officially introducing the mechanism to the world.
- 1805 – The tourbillon is first publicly presented at the National Exhibition of Industrial Products in Paris.
- 1806 – Breguet starts producing commercial tourbillon pocket watches in limited numbers.

What are the Main Components of A Tourbillon Movement
A tourbillon movement consists of several intricate components that work together to counteract the effects of gravity and enhance timekeeping precision.
1. Tourbillon Cage (Carriage)
- A rotating frame holding the escapement and balance wheel
- Made from lightweight materials like titanium to reduce energy consumption
2. Balance Wheel
- The oscillating component that regulates the timekeeping of the watch
- Works with the hairspring for consistent and accurate oscillations
- The constant rotation of the tourbillon cage helps equalize errors caused by gravity
3. Hairspring (Balance Spring)
- A delicate, coiled spring regulating the oscillation of the balance wheel
- Made from materials such as Nivarox or silicon to improve stability and reduce temperature sensitivity
- A properly calibrated hairspring is essential for precision in a tourbillon.
4. Escapement
- Composed of the escape wheel and pallet fork, it transfers energy from the mainspring to the balance wheel.
- The pallet fork locks and releases the escape wheel at precise intervals, maintaining the watch’s ticking rhythm.
- In a tourbillon, the entire escapement rotates, ensuring uniform distribution of gravitational effects.
5. Fixed Fourth Wheel (Stationary Wheel)
- A stationary gear that meshes with the rotating cage, allowing the tourbillon to function
- The escape wheel engages with this fixed wheel to maintain the proper function of the escapement.
6. Pinion and Gear Train
- Transmit energy from the mainspring barrel to power the tourbillon
- Makes sure the rotation of the tourbillon cage does not interfere with the timekeeping mechanism
7. Tourbillon Bridge or Flying Mount
- Traditional tourbillons are supported by a bridge on both sides, securing the rotating cage.
- Flying tourbillons eliminate the upper bridge, allowing for an unobstructed view of the mechanism.
8. Mainspring Barrel
- The power source of the movement. This component supplies energy to drive the tourbillon mechanism
- In some high-end tourbillons, multiple mainspring barrels are used to ensure consistent torque and longer power reserves.
9. Tourbillon Regulator
- Adjusts the rate of the balance wheel to maintain accuracy
- Fine-tuned by master watchmakers for optimal performance
How Does a Tourbillon Watch Work?
From the most expensive to the cheapest tourbillon watch, the workings of a tourbillon movement follows the same general principle in this step-by-step breakdown of how it works:
1. Power Transmission from the Mainspring
- The mainspring in the barrel stores and releases energy as it unwinds.
- This energy is transferred through the gear train, powering the entire movement.
2. Regulation of Timekeeping
- The gear train delivers power to the escapement, which controls the release of energy in small, precise increments.
- The balance wheel oscillates back and forth, regulated by the hairspring for consistent timekeeping.
3. Rotation of the Tourbillon Cage
- Unlike traditional mechanical movements, a tourbillon cage houses the escapement and balance wheel.
- This cage rotates continuously, completing one full revolution per minute.
- As it rotates, the escapement and balance wheel experience different positional orientations, averaging out gravitational errors.
4. Eliminating Gravity-Induced Errors
- In a regular mechanical watch, the balance wheel is affected by gravity when the watch remains in one position for too long.
- By constantly rotating, the tourbillon distributes these effects more evenly, reducing deviations in timekeeping.
5. Time Display
- Despite the rotating escapement, the gear train and hands remain stationary, driven by the energy regulated through the tourbillon mechanism.
- The hands move across the dial as in a conventional watch while the tourbillon continues its rotation.
What Are Different Variations of Tourbillons?
Tourbillon watches have evolved significantly since Abraham-Louis Breguet first introduced the mechanism in 1801. Today, several variations exist, each showcasing different levels of complexity and craftsmanship. Here are the most notable types of tourbillons:
1. Classic (Traditional) Tourbillon
The original single-axis tourbillon rotates the escapement and balance wheel in a fixed cage at one revolution per minute. It's designed to compensate for gravity-induced errors in pocket watches held in a vertical position.
Example Tourbillon Watches:
- Breguet Classique Tourbillon Extra-Plat 5367
- Patek Philippe 5316P Grand Complication
2. Flying Tourbillon
Invented by Alfred Helwig in 1920, the flying tourbillon is supported from below, making the upper bridge unnecessary. This creates the illusion that the tourbillon is “floating” inside the movement.
Example Tourbillon Watches:
- Glashütte Original Senator Flying Tourbillon
- Audemars Piguet Royal Oak Offshore Flying Tourbillon
3. Multi Axis Tourbillon
Unlike traditional tourbillons that rotate on a single axis, multi-axis tourbillons rotate on two or three axes, further negating gravitational errors. These mechanisms are extremely complex and require advanced engineering.
Variations:
- Double Axis Tourbillon: Rotates in two directions.
- Triple Axis Tourbillon: Rotates in three directions for greater precision
Example Tourbillon Watches:
- Jaeger-LeCoultre Gyrotourbillon (multi-axis)
- Greubel Forsey Double Tourbillon 30° (double-axis)
- Vianney Halter Deep Space Tourbillon (triple-axis)
4. Double and Quadruple Tourbillon
These watches feature two or four separate tourbillon cages, either working independently or connected via a differential. These designs increase accuracy by averaging out timing errors.
Example Tourbillon Watches:
- Greubel Forsey Double Tourbillon 30°
- Greubel Forsey Quadruple Tourbillon
5. Gyrotourbillon (Spherical Tourbillon)
Introduced by Jaeger-LeCoultre, this highly advanced multi-axis tourbillon moves in a three-dimensional spherical motion. It significantly reduces timing deviations caused by gravity.
Example Tourbillon Watches:
- Jaeger-LeCoultre Master Grande Tradition Gyrotourbillon
6. Tourbillon with Additional Complications
Tourbillons are often paired with other complications, such as minute repeaters, perpetual calendars, or chronographs. The combination increases both the technical difficulty and the prestige of the timepiece.
Example Tourbillon Watches:
- A. Lange & Söhne Datograph Perpetual Tourbillon (Chronograph + Perpetual Calendar + Tourbillon)
- Vacheron Constantin Traditionnelle Minute Repeater Tourbillon
7. Carrousel Tourbillon
Developed by Bahne Bonniksen in the late 19th century, this mechanism is similar to a traditional tourbillon but with a slightly different power distribution system.
Example Tourbillon Watches:
- Blancpain Carrousel Tourbillon
8. High-Frequency Tourbillon
These are tourbillons that operate at a higher beat rate (e.g., 5Hz or 10Hz) for improved timekeeping accuracy. These require cutting-edge materials such as silicon escapements to handle the increased frequency.
Example Tourbillon Watches:
- Zenith Defy Double Tourbillon (50Hz escapement!)
- Breguet Classique Chronométrie 7727 (10Hz tourbillon)
