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.

For the Astronomia Art Dragon Platinum, the base of the platinum case reveals a 3D hand-engraved 18K gold dragon with ruby eyes that is carefully placed within the four arms of the Astronomia movement. The dragon and complications are mounted on a base made of Blue Grade 5 titanium with 18K gold hand-engraved and applied stars and zodiac signs.

The mythical dragon is a magnificent creature, representing
strength and power, glory and good fortune. The creation of the 18K dragon
combines high technology with Old World artisan skills.

The Jacob & Co. artisan who crafts the dragon first uses
Computer-Aided-Design (CAD) to detail the sculpture and plan its placement
inside the watch. From this rendering, the 18K gold cast is made. This process
alone takes more than two months. Then another three months is spent by the
artisan to hand-sculpt the details of the dragon. Every surface is carved,
engraved, and polished.

Finally, the movement is assembled around the sculpture, with
care taken to ensure it doesn't obstruct the perfect functioning of the watch.

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 additional axes in which the tourbillon turns.

For the Astronomia Art Dragon Platinum, the tourbillon is double-axis - turning in two axes: one in 60 seconds and the second in 2.5 minutes.

The base of the dial is made of blue Grade 5 titanium with 18K gold hand-engraved and applied stars and zodiac signs.

Customization and bespoke work have been the foundation of Jacob & Co. since the beginning and continues to this day. The brand has created several Astronomia Art pieces - Dragons, Spiders, Octopi, Horses, Tigers, world cities and more. Visit any Jacob & Co. point of sale or contact the brand directly to inquire.

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 contemporary 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. For the Astronomia Art Dragon Platinum, the 1-carat Jacob-cut diamond does a complete rotation every 30 seconds.

The globe is made of magnesium to ensure consistency in weight, as all four satellites must weight exactly the same. It's finished in blue lacquer. The globe performs a complete rotation every 30 seconds.

The Roman numerals on the skeletonized dial are hand-engraved and filled with blue lacquer, while the hand-finished hands appear in gun blue metallic.

The Astronomia Art Dragon Platinum case measures 47 millimeters in diameter and 25 millimeters in thickness between the highest point of its specially curved front sapphire crystal and the lowest point of its case. The case features four sapphire crystal windows installed throughout the periphery, allowing for unhindered viewing of the caliber and the artwork inside.
