When the Astronomia Tourbillon was introduced in 2014, the re-invention of the tourbillon in a vertical orientation and the constant turning of its four satellites garnered most of the attention.

What led to the development of the Astronomia Art Collection, however, is the incredible sapphire crystal and precious metal case, which puts everything inside on display.

Soon arose the idea to develop special works of art to put inside the Astronomia Tourbillon, using its sapphire crystal and precious metal case as a gallery, while still showcasing the incredible Astronomia tourbillon movement. The brand started with dragons, octopi, spiders, horses and more. Incredibly successful, Jacob & Co. has expanded the Astronomia Tourbillon Art Collection every year since. Now comes the Astronomia Art Color Tigers.

The tiger is a universal symbol of beauty, grace and absolute strength. In a uniquely vivid interpretation of the beast's feral and wild beauty, the world's largest feline is the focus of the latest Astronomia Art piece from Jacob & Co.

The nobility of the world's most majestic cat never ceases to inspire jco. The Astronomia Art Color Tigers is a unique piece. Its piece de resistance is a pair of them as backdrop for the rotating Astronomia movement. On a wide plate made of white gold, a master engraver has etched the profiles and outlines of two tigers in a wildly aggressive posture in a stylized jungle environment.

Fangs and claws have come out as they're ready to pounce on their prey. The vividness of the scene is enhanced by artful painting, the kind of which can only be achieved by the most skilled artisans ion the field.

The tourbillon was originally invented to be a single-axis, rotating cage to carry the regulating organ of a mechanical watch for improved timekeeping performance. The Astronomia Art Color Tigers presents this 224-year-old invention in a yet more spectacular way. It rotates along two axes. One is horizontal with a rotation speed of 1 per minute. The other is vertical, with a rotation speed of one every 2.5 minutes. And as the entire movements spins on its central axis in 10 minutes, this is in fact a triple-axis movement.

The tourbillon of the Astronomia Art Color Tigers features a delicately decorated cage that encapsulates the balance wheel, hairspring and escape wheel. This openworked cage is only secured from underneath, which makes it a flying tourbillon. It is a constellation of superbly finished components that, when assembled and fine-tuned expertly, allows calibre JCAM18 to keep accurate time throughout its 60-hour power reserve.

Customization and bespoke work has been the foundation of Jacob & Co. since the beginning and continues to this day. The brand has created a number of Astronomia Art pieces - Dragons, Spiders, Octopi, Horses, Tigers, world cities and more.

The Astronomia Art Collection has become an icon within the brand and collectors look to Jacob & Co. to see what's coming next. The Astronomia Art is a showcase of Jacob & Co.'s commitment to using traditional métiers d'art in a modern way.

Jacob & Co. has been on the forefront of using precious stones since its founding in 1986, and has developed a number of special cuts and setting techniques. For the Astronomia Tourbillon, the brand developed the 288-facet Jacob-cut diamond.

This special cut can be accomplished by only a select few gem cutters, and the rough stone typically starts out double the size of the finished diamond. The facets have to be incredibly precise so the diamond is perfectly symmetrical and round. In the Astronomia Art, the one carat Jacob-cut diamond rotates on itself in 30 seconds.

The globe is made of magnesium to ensure consistency in weight, as all four satellites have to weight exactly the same. The globe rotates on itself in 30 seconds.

The Astronomia Art Color Tigers's case measures 50 millimeters in diameter and 25 millimeters thick. Crafted from 18K white gold, the case features four sapphire crystal windows installed throughout the periphery, allowing for unhindered viewing of the spectacular caliber and the artwork inside.

The time display sub-dial of the Astronomia Art Color Tigers is driven through an infinitesimal differential system that allows it to always remain in the correct, 12/6 position as it rotates. The Roman numerals on the skeletonized dial are hand-engraved and filled with black lacquer, while the hand-finished hands appear in gun blue metallic.
