Four-axis tourbillon. A world first, donated to watchmaking’s most prestigious charity. This is a technical achievement. This is a recognition of the deep and fruitful partnership between Jacob & Co. and the Concepto wholesale fashion watches factory. This proves that being “inspired by the impossible” can make the impossible a reality.

The Astronomia Revolution 4th Dimension is equipped with a three-axis flying tourbillon at the end of a two-armed merry-go-round. It rotates every 60 seconds. This makes it a four-axis tourbillon, the first of its kind to be installed in a wristwatch. What’s more, the tourbillon cage contains a high-frequency constant-force escapement.

The Fourth Dimensional Astronomical Revolution is not just an unheard of complication. Its execution is also carried out from another dimension. In keeping with the Only Watch 2023 color theme, it contains 35 colored stones, culet-up. A kinetic work of mechanical art and a jewelry achievement, Astronomia Revolution 4th Dimension is more than just a unique piece. This is a ship like no other.

Just four months after launching the groundbreaking Astronomia Revolution, Jacob & Co. is once again pushing innovation to the limit. The Astronomia Revolution 4th Dimension is an enlarged and upgraded three-axis tourbillon one-minute rotation movement. Jointly developed, launched and contracted with Concepto Watch Factory, Jacob & Co.’s main movement partner, the Astronomia Revolution 4th Dimension features a four-axis flying tourbillon.

This watchmaking achievement is the brainchild of Valérien Jaquet, Founder, Master Watchmaker and CEO of Jacob & Co. and Concepto Watch Factory. “For almost 20 years, the Concepto watch factory team and I have had a deep and close relationship with the Jacob & Co. brand and Jacob Arabo himself,” said Valérien Jaquet. Only Watch and the values conveyed by this charity auction deserve our closer cooperation to deliver a timepiece of exceptional mechanical and aesthetic quality. As tourbillon specialists, we are very proud to have co-signed this world-first project with Jacob & Co. to aid in the research of Duchenne muscular dystrophy.

“From the very beginning of the Astronomia series, I wanted it to spin as fast as possible, and we got to a minute with Astronomia Revolution,” said Jacob Arabo. I hope it’s a phenomenal tourbillon, and then we get to the quadcopter. This is the first time a timepiece breaks the three-axis tourbillon barrier. Together, Jacob & Co. and Concepto Watch Factory decided that this level of ingenuity and expertise had to be brought to Only Watch, a charity so unanimously recognized. “

Crystal structure
The Astronomia Revolution 4th Dimension is a unique piece that will be auctioned on November 5th and will benefit Only Watch in the fight against Duchenne muscular dystrophy. The Astronomia Revolution 4th Dimension is more than just an implemented sports concept. Jacob & Co. is a watchmaker and jeweler and the Astronomia Revolution 4th Dimension is a fine watchmaking and fine jewelry creation.

The part beneath the carousel is a rose gold structure crafted like a large piece of fine jewelry. Jacob & Co. set 35 gemstones in this openwork structure, chosen from 7 types of gemstones. Each one is custom cut to create a field of colored light. Place each pointed bottom side up. The layout intentionally feels random, creating jagged expanses of space. It captures light, reshapes it and sends it back, and shades and enhances it. The fourth dimensional astronomical revolution is a mechanical achievement from another dimension or crystalline planet. wholesale fake watches

Expand horizons
Jointly developed with the Concepto Manufacture, the JCAM 54 caliber has the same construction as all other Astronomia calibers. Only a small portion is hidden by a decorative plate set with 35 gems. From the center, the rest of the movement emerges in the shape of a two-armed merry-go-round. This represents the majority of the movement’s 485 parts, which make one revolution every 60 seconds. It acts like a seconds hand and is the first axis of rotation of the tourbillon.

At the end of the first arm, the first axis of rotation, there is a flying three-axis tourbillon. Fly because the tourbillon cage is supported by only one end (the lateral one). Three axes because the escapement rotates through three sets of gears. The first spin takes 60 seconds, the second 18 seconds, and the last 15 seconds. This is not only a large number of axes, but also very high speeds. The principle of the tourbillon is to increase the number of positions the escapement occupies in space. The more positions and the faster the speed, the better the tourbillon can balance the negative influence of gravity on its precise time measurement. With four axes and such a fast rotation, the Astronomia Revolution 4th Dimension provides tourbillons with the best parameters never seen before.

energy core
These rotational speeds require a lot of energy. And even more so with the spin of the carousel. Such a strong flow of water could easily damage the escapement if it was passed directly to it. To take advantage of the influx of resources, Jacob & Co. and the Concepto watch factory devised a way to protect the escapement, a constant-force device for which a patent is pending. Every 1/6 of a second (that is, the frequency of the balance wheel), the gear train activates a whip. It acts as a buffer between the barrel and the flow of energy to the tourbillon.

Each time the whip is activated, it transmits the energy required by the escapement for the next 1/6 second. Also, as this would undersupply the balance wheel. No more, or the tourbillon and the entire rotating platform would be overloaded. Apart from the obvious benefit of retaining the escapement, this has important timekeeping advantages. When combined with the extreme position afforded by the four tourbillon axes, this unique creation from Jacob & Co. x Concepto Watch Factory undoubtedly enters the fourth dimension of watchmaking.

Observation deck
The rose gold case has a diameter of 47 mm and an overall height of 27 mm. These dimensions reflect the dimensions of the JCAM 54 movement. Such a spectacular work of watchmaking art needs to be appreciated from every possible angle. The Astronomia case is built around curved sapphire glass panels held together by precious metal. Best of all, the wide domed sapphire crystal allows you to see both the JCAM 54 movement and what lies beneath.

It is a combination of shape, color, gem variety and gem cut. The backplate of the Astronomia Revolution 4th Dimension is a work of art, something like it is often seen in cathedrals. Except this one is made of gemstones. There are 35 in total, of 7 different types, each available in a different color. Golden garnet garnet is orange in color. Citrine is yellow in color. Sapphire is blue. Tsavorite is green. Rudolph garnet is purple in color. Topaz is light blue and pyrope garnet is red.

alien landscape
Each stone is cut to a custom shape and is not part of any classic cut. Also, they are not placed the way gemstones are usually, with the table up and the culet down.fake Jacob & Co. took the opposite decision, creating a geometric field, an uneven landscape of crystals and light. Founder, Chairman and Creative Director of Jacob & Co. Jacobarabo is a huge fan of all things space-related. His passion gave birth to the Astronomia collection. Again, it takes on a new, imaginative shape, like one would expect to see on a Star Trek episode or the moon-orbiting planet Krypton. Jacob Arabo was a pioneer in the use of colored gemstones back in the 1980s, incorporating his taste for reds, blues, oranges, yellows and greens into numerous timepieces. Before the term rainbow mosaic became popular, many high-end jewelry watches have adopted the rainbow mosaic process. Many other mountains are known as Mount Alequino, Mount Camo or Mount Peru, a nod to the colorful formations of Vini Cuenca, also known as Rainbow Mountain. The color gamut of the Astronomia Revolution 4th Dimension is actually an updated form of Jacob & Co.’s signature. Like the JCAM 54 movement, it is an extra step towards “drawing inspiration from the impossible”.
