Astronomia Octopus Baguette

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 on display.

So, the idea was to develop special works of art to put inside the Astronomia Tourbillon, using its massive sapphire crystal 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.

High Watchmaking Serving High Art

Graceful, flexibility, creativity, intelligence, unpredictability - these traits are all attributed to the Octopus, which is too often seen as a monster from the sea. The Astronomia Art Octopus combines an intricate titanium sculpture with sophisticated miniature painting. The resulting work of art, placed on top of the Astronomia Tourbillon four satellite structure, is a triumph of artistry.

The sculpture itself takes at least three months to create, then the miniature painters get to work, working their magic with tiny brushes and special paints, bringing the Octopus to life.

Below the movement is the base dial completely set with 281 baguette white diamonds ( 9.89cts), and the lugs of the 18K rose gold case are also set with 80 baguette diamonds ( 6.10cts). Only Jacob & Co., with its years of experience as a jewelry brand, has the expertise to combine high jewelry, high watchmaking, and metier d'art.

The Tourbillon

The tourbillon is widely considered the ultimate complication, as it turns and spins to counter the effects of gravity on the precision of the movement. For the Astronomia Collection,Jacob & Co. has taken the tourbillon one step farther, introducing an additional axis in which the tourbillon turns. For the Astronomia Art Octopus Baguette, the tourbillon is double-axis - turning in two axes: one in 60 seconds and the second in 2.5 minutes..

The base dial of this timepiece is invisibly set with 257 Baguette Icy Blue Sapphires (≈ 9.88 ct.). The result is an impressively intricate and attractive timepiece with a base dial entirely covered in precious white diamonds using the difficult and sophisticated "invisible setting" (meaning none of the supporting metal is visible).

The Jacob-Cut Diamond

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 Magnesium Globe

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

The Astronomia Art Octopus Baguette's case measures 50 millimeters in diameter and 25 millimeters thick between the highest point of its specially curved front sapphire crystal and the lowest point of its case. Crafted from 18K rose 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 lugs are invisibly set with baguette-cut white diamonds.


The time display sub-dial of the Astronomia Octopus Baguette is driven through an infinitesimal differential system that allows it to always remain in the correct, 12/6 position as it rotates together with the movement's four-armed platform across the front of the Astronomia. 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.
