What is a Tourbillon and Why Is It So Expensive? The Fascinating Story of Horological Genius

If you start getting into watches, you’ll soon discover that the tourbillon is one of the most myth-shrouded and admired complications. It signals luxury, craft perfection and technical difficulty. But what exactly is a tourbillon, and why can watches with this device cost hundreds of thousands or even millions? Let’s explain it plainly yet in depth.

What is a tourbillon?
The word tourbillon comes from French and means “whirl” or “rotation.” In watchmaking it names a special mechanism inside mechanical movements. A tourbillon aims to improve accuracy by cancelling the negative effect of gravity on the escapement.

How does it work?
The balance wheel, hairspring and escapement set a watch’s accuracy. Gravity pulls on these parts differently depending on whether the watch is horizontal, vertical or on its side. A tourbillon mounts the entire escapement in a rotating cage that turns around its axis—usually once every 60 seconds—so positional errors average out. Result: theoretically better timekeeping.

Who invented the tourbillon?
The genius was Abraham-Louis Breguet, who patented the tourbillon in 1801 to solve accuracy problems in pocket watches, which sat upright most of the time. His answer was to rotate the escapement.

Is the tourbillon really useful?
In Breguet’s era, yes: pocket watches suffered huge positional errors. Today we wear watches on the wrist, constantly changing orientation, which already averages those errors. For modern users a tourbillon isn’t necessary for accuracy; it mainly showcases watchmaking skill, luxury and prestige—like owning a Ferrari.

Why is a tourbillon so expensive?
Building one is extremely complex and time-consuming. Every part must be perfectly balanced so the cage neither drags nor races. Much of the work is hand-done by a handful of master watchmakers, and top brands may spend hundreds of hours on a single tourbillon, often in limited series—hence sky-high prices.

Tourbillon in modern watches

Classic single-axis tourbillon
Most turn on one axis, usually once per minute; found at Breguet, Jaeger-LeCoultre, Zenith.

Double or triple tourbillon
Some watches house two or three cages rotating on different planes to counter gravity even more, e.g., Greubel Forsey Double Tourbillon, Jaeger-LeCoultre Gyrotourbillon.

Flying tourbillon
Mounted only on one side, it seems to “float” and offers a better view; invented by Glashütte Original.

Why do people want a tourbillon?
– Prestige – signals high status
– Technical fascination – owners love watching the rotating cage
– Collectability – limited models often gain value
– Craft symbol – proves what human hands can create

How much do tourbillon watches cost?
The cheapest Chinese tourbillons start around €1 200 (quality debatable). Serious Swiss or German pieces begin near €16 000 and top brands climb into the millions, for example:
Breguet Classique Tourbillon – about €60 000
Audemars Piguet Royal Oak Tourbillon – €80 000 – €200 000
Greubel Forsey Double Tourbillon – over €400 000

Common myths about the tourbillon
“Tourbillon guarantees perfect accuracy.” → Modern movements are already very accurate without it.
“Every tourbillon is handmade.” → Cheaper ones can be machine-produced.
“Tourbillons never break.” → They still need service and can be delicate.
“Only luxury brands use tourbillons.” → Chinese makers offer cheaper versions, though quality differs.

FAQ – Frequently asked questions

Does a tourbillon improve accuracy?
In theory yes, but in daily wear the difference is minor.

Why is a tourbillon so expensive?
Because its construction is extremely complex and it’s a luxury symbol.

Is a tourbillon just marketing?
Partly. Today it’s more about prestige and technical beauty than pure function.

Are there inexpensive tourbillons?
Yes, but build quality and longevity are often lower.

Can I play sports with a tourbillon?
Not recommended—the mechanism is delicate and sensitive to shocks.

How many axes can a tourbillon have?
Basic models have one; double and triple tourbillons also exist.
