Story

Jacob & Co. is proud to showcase the Astronomia Tourbillon Moscow pièce unique, featuring four 3-D hand-engraved and hand-painted iconic Moscow buildings on an aventurine base.

Moscow is one of the world's most important and largest cities. Founded in 1147, the city is situated on the Moskva River, which winds through the city - 49 bridges span the river within the city limits. Moscow is the centerpiece of Russian culture, religion, art, government, business, and education.

The exquisitely finished buildings inside the gallery of the Astronomia Art Moscow are:

THE DOUBLE-AXIS TOURBILLON

Powering this incredible timepiece is the iconic Jacob & Co. double-axis tourbillon movement, featuring four satellite arms. The tourbillon is on one arm, turning on two axes, one in 60 seconds and the second in five minutes.

On the second satellite is the 288-facet Jacob-cut diamond, rotating on itself in 60 seconds. On the third satellite, directly across from the tourbillon, is the time display, while on the fourth satellite is the magnesium lacquered globe, which rotates on itself in 60 seconds.

CUSTOMIZATION

Since the Astronomia Tourbillon was introduced in 2014, the amazing sapphire crystal of the case was envisioned as a "gallery" of sorts to display first the incredible Astronomia triple-axis movement, then this evolved into displaying special works of art. The brand started with Dragons, Octopi, Spiders, Horses and more. Incredibly successful since it began, Jacob & Co. has expanded the Astronomia Tourbillon Art Collection every year since.

Moscow is one of Jacob & Co. founder Jacob Arabo's favorite cities, and the Astronomia Tourbillon is the ultimate showcase for these amazing artistic creations. Customization and bespoke work has been the foundation of Jacob & Co. since the beginning and continues to this day. The brand is definitely open to making custom watches of all the great cities of the world. 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 pièce unique Astronomia Art Moscow is an incredible tribute to this fascinating city and a showcase of Jacob & Co.'s commitment to using métier d'art in a modern way.

Saint Basil’s Cathedral

Saint Basil's Cathedral, a Christian church in Red Square, is one of the most famous monuments in the world. Designed to look like the flame of a bonfire, it is known as "the flame of Moscow."

The Cathedral of Christ the Saviour

The Cathedral of Christ the Saviour, a resplendent Russian Orthodox cathedral on the banks of the Moskva River, is famous for its gold-colored domes and Byzantine architecture.

The Bolshoi Theatre

The Bolshoi Theatre, the historical center of Russia's performing arts, was opened on Tsar Alexander II's coronation day in 1856. Home to the Bolshoi Ballet and the Bolshoi Opera, the oldest and most renowned companies in the world, the Bolshoi Theatre is famous the world over.

Hotel Ukraina

Hotel Ukraina is one of the "Seven Sisters" of neo-classical Stalin-era buildings located in Moscow, and it was once the tallest hotel in the world. A true landmark of the city, it remains a hotel today, and a five-star luxury one at that.

FOUR SCULPTURES

These four buildings are hand-engraved and hand-painted by traditional métiers d'art artisans. Many hours of hand work go into these miniature works of art. They are, in turn, set into an aventurine base, a beautiful glass that looks like a starry sky.

288-FACET JACOB-CUT DIAMOND

The Jacob-Cut diamond starts out as a much larger rough diamond. First, a rough diamond big enough has to be found, and the purity, clarity, and color has to be of the highest quality both inside and out, and there can be no inclusions. If they start to cut the diamond and find an inclusion, the entire piece will be ruined.

Next, the diamond is cut by machine into a round shape, close in size to the final diamond.

Then, the gem cutter shapes the stone by hand, cutting each individual facet (of 288). This has to be done slowly and carefully, as the stone has to be perfectly round and symmetrical. The danger is that the stone will become oblong and not round. To be used in the Astronomia Collection, the Jacob-cut diamond has to be completely round and weigh exactly as much as the other three satellites (time display, triple-axis tourbillon, magnesium globe).

During the process, if the gem cutter puts slightly too much pressure while adding the facets, too much of the diamond will be cut away, and the ball will end up smaller than the desired diameter. The cutting process takes at least two weeks of dedicated, painstaking work.

To make the final one-carat, Jacob-cut diamond with 288 facets, more than half of the initial rough diamond will be cut away.

The complexity of cutting the 288 facets by hand and making sure everything is symmetrical and the diamond is absolutely round, is what makes the Jacob & Co. diamond used in the Astronomia collection so special.

CASE & CRYSTAL

The Astronomia Art Moscow'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.

DIAL & HANDS

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.
