The Astronomia Table Clock presents the wonder of Astronomia in a bold new way: as a majestic and beautifully crafted table clock. Its four-arm movement spins and floats in this space of mineral crystal and stainless steel, crafted to amaze every eye. Filled with unique watchmaking solutions and featuring the latest haute horlogerie techniques, the Astronomia table clock is an unrivaled icon in haute horology; repackaged to become the centerpiece of even the most extravagant exhibition space.

Exclusive astronomical movement

The four arms of the Astronomia table clock carry the timekeeping mechanism of the watch, the hand-painted blue magnesium sphere shows the spectacular view of the earth, in stark contrast to the real meteorite of extraterrestrial origin, and the skeletonized dial with differential levels. time display. This four-armed assembly, which completes a rotation around the center of the watch in 10 minutes, is surrounded from the front and on each side by an anti-reflective treated mineral crystal aperture. Another stunning feature of the Astronomia table clock is that each pair of opposing arms is perfectly calculated to counterweight each other – a testament to unparalleled material engineering and watch movement design. So, in a rather poetic way, real meteorites are cut to have the exact same weight as the magnesium-clad Earth on the other side.


American writer Jack London once said: “I would rather be a beautiful shooting star, so that every atom of me exudes a magnificent light, than a sleeping eternal planet.”

There is something magical about meteorites, not only their unique appearance, but knowing that they do not belong on this earth. There is something truly special about having a meteorite on top of an Astronomia clock that you can always admire. Best replica watches

Meteorites are extremely rare, and the meteorite in the Astronomia desk clock comes from the Campo del Cielo crater field discovered in 1576. Cutting a meteorite is no easy feat, and this one has been cut to reveal the distinctive streaks inside.

The real meteorite was found in the sporadic Campo del Cielo site in Argentina, about 1,000 kilometers northwest of Buenos Aires. The Campo del Cielo iron meteorite, which fell between 4,200 and 4,700 years ago, created more than 20 craters over a large area of several square kilometers during the impact; the largest crater is about 100 meters in diameter.

The fragment inside the observatory clock is part of a larger meteorite that was cooled with liquid nitrogen and then broken into smaller pieces. These fragments are broken along the octahedral planes; revealing the crystal structure.

This sky has found a permanent home in the beautiful Astronomia Table Clock.

It takes 10 minutes for the meteorite to circle the dial with the other moons.

Aluminum Globe

The globe is made of blue painted aluminum with gold continents to ensure weight consistency, as all four satellites must be approximately the same weight. It takes 30 seconds for the globe to rotate once on its axis and 10 minutes to complete one revolution around the dial. JACOB & CO ASTRONOMIA CLARITY WHITE DRAGON

Case and crystal

The case of the Astronomia table clock has a diameter of 128 mm and a thickness of 85 mm, between the highest point of its specially curved front crystal cover and the lowest point of the case. Beautifully crafted in stainless steel, the case is surrounded by four mineral crystal windows, ensuring a viewing experience through large mineral crystal front apertures, allowing unobstructed views of the spectacular movement within. The Astronomia desk clock is best appreciated when the case is opened and the front cover is used as the basis for its standing configuration.

dial and hands

The time display sub-dials of the Astronomia desk clock are driven by a differential system so that they remain horizontal and legible as they rotate 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 have a gunmetal blue metallic finish. The “Skylayer front case” that serves as the backdrop for the JCAM17 caliber is made of segmented stainless steel and is inlaid with a pool of shimmering blue aventurine: an artistic representation of the starry sky on a clear night.

At first glance:

Four satellite arms in constant motion, rotating every 10 minutes on the aventurine dial

The blue lacquered aluminum sphere rotates on its own every 60 seconds and on the aventurine dial every 10 minutes
