Frequently Asked Questions

What is a tourbillon?

A tourbillon is a rotating cage that contains the escapement (balance wheel, pallet fork, and escape wheel) of a mechanical watch. It rotates continuously — typically once per minute — to average out positional errors caused by gravity, improving accuracy.

What is the difference between a classic and a flying tourbillon?

A classic tourbillon is supported by both a top and bottom bridge, while a flying tourbillon is cantilevered from below with no visible upper support. Flying tourbillons offer an unobstructed view of the rotating escapement and are considered more aesthetically demanding to construct.

Does a tourbillon actually improve accuracy?

In modern wristwatches, the accuracy benefit is minimal since positional errors are already well-compensated. However, in pocket watches (where the tourbillon was invented in 1801 by Breguet), the constant rotation eliminated rate differences between vertical positions. Today, tourbillons are primarily a demonstration of high horological artistry.

# Tourbillon Visualizer: Animated Watch Escapement Art

The tourbillon is one of the most captivating complications in haute horlogerie. This interactive visualizer brings the rotating escapement to life with a detailed animated rendering of the balance wheel, hairspring, pallet fork, escape wheel, and the iconic rotating cage. Explore the mechanical poetry of Breguet's masterpiece.

# How a Tourbillon Works

A tourbillon houses the entire escapement — balance wheel, hairspring, pallet fork, and escape wheel — inside a rotating cage. The cage typically completes one rotation per minute, continuously changing the position of the escapement relative to gravity. This averages out positional timing errors, a concept that was revolutionary when Abraham-Louis Breguet patented it in 1801. The balance wheel oscillates at the watch's beat rate (typically 4 Hz / 28,800 vph), while the escape wheel advances one tooth per beat, creating the characteristic ticking motion.
