The Cone Tourbillon: 10 Years of Watchmaking Revolution
The new HYT Conical Tourbillon is a hypnotic technical response to the promise made by the Neuchâtel company ten years ago: to bring high-end watchmaking into the future. A symbiosis of science and the expertise of the best watchmakers, this mechanical fluid watch features a conical tourbillon. Created by master watchmaker Eric Coudray, he drew inspiration from the unique inclined balance tourbillon developed by Walter Prendel in 1928, and provided a new solution for improving the stability and performance of the tourbillon.

Ten years old, it's time to be bold.
At the age of ten, the temperament and character are established. This is a time of boldness and passion. By the age of ten, children develop a powerful energy that satisfies their desire to grow and develop. But it's also a phase that allows for more structured experimentation.

Based on this concept, the new HYT Conical Tourbillon watch is a pure return to the brand's creative source, fully reflecting its unique personality.

It is both vivid and sensual thanks to the double movement effect created by the retrograde fluid hour markers and the dynamic movement of the conical tourbillon. HYT Conical Tourbillon is a new form of life marked by a central mechanism at its core.

On the wrist, the captivating lines and finishes of the HYT Cone Tourbillon are on full display. This piece symbolizes the perfect marriage of modern approaches to watchmaking with the finest creations of Swiss watchmakers. The attentive eye will spot the sandblasted and satin-finished finish of Caliber 701 TC, a hand-wound mechanical movement beating at 21,600 vibrations per hour (3 Hz).

More discerning lovers of fine watchmaking will be interested in the specifications of the suspended tourbillon movement, which has a sprung balance inclined at 30 degrees from the horizontal, a 15-degree escape wheel and a 23-degree pallet fork. This bold technical achievement draws inspiration directly from the work of German watchmaker Walter Prendel and his tilting balance tourbillon.

When Eric Coudray zooms in on Prendel's tourbillon


The tourbillon is a mechanical device invented by Abraham-Louis Breguet to improve the accuracy of mechanical watches by counteracting the disruption of the isochronism of the balance by gravity. Its principle is to place the regulator and escapement of the movement in a cage that rotates around its own axis to obtain a range of vertical positions and ensure mutual compensation, thus getting rid of the pull of the earth.

Watchmakers have been perfecting this system for more than two centuries, from the original principle patented by Abraham-Louis Breguet in 1801 to Omega's central tourbillon in 1995. There are countless interpretations and variations on this theme.

However, one of the most important steps in the development of the tourbillon is not one of the most famous. This is a diagonal tourbillon developed by German watchmaker Walter Prendel in 1928.

Walter Prendel in his workshop in Groitzsch, Saxony, a region as famous as Switzerland for the development of cutting-edge watches, the rate stability and regularity of his inclined tourbillon and Spring balanced with 30° horizontal inclination. This will be demonstrated by creating a unique pocket watch equipped with his ingenious mechanism to complete a revolution in 6 minutes. A key milestone, the historic timepiece has not been seen since it was sold at auction in Geneva in 2021.

It was at the beginning of the 2020s that Prix Gaïa winner and master watchmaker Eric Coudray, who was familiar with Walter Prendel's complex works, decided to continue this work to improve the tourbillon and build on this inclined tourbillon. Eric Coudray designed his conical tourbillon, which he called the "Cônillon", a revision and reinterpretation of Prendel's inclined tourbillon.

Given its advances in contemporary fine watchmaking, HYT's decision to include a tourbillon in the design of its new watches' mechanical movements was logical. Of course, the independent company turned to Eric Coudray, who has been closely involved with the brand's development over the years, to help it achieve this goal.

Just as the ebb and flow of liquid in a HYT watch is clear at a glance, the function of the Cone Tourbillon requires no magnifying glass or other tools, and any discerning watch lover can understand it through an unusual dynamic animation.

At the very center of the dial, the conical tourbillon rotates clockwise once every 30 seconds, and three spheres rotate at different speeds for easy observation: the first completes four revolutions per minute, the second completes five revolutions per minute, and The third six laps are one minute, clockwise.

These rotations introduce a particularly daring form of confusion because, paradoxically, they demonstrate the stability of the rate of the conical tourbillon. Any observer would intuitively think that their contradictory forces would be disruptive, disrupting the balance, which would seem to run counter to the strict logic of watchmaking.

Instead, they demonstrate the perfect stability of the tourbillon's rhythm, because unlike other types of animation, which are located after the balance wheel in the kinetic chain, the animation sphere in the HYT Cone Tourbillon is moved by four cylinders to reach the regulating mechanism.

The disconnected rapid movement of the animated spheres ensures the exact timing of the conical tourbillon, a tangible demonstration of its technical efficiency.
