The Astronomia is the epitome of 21st century haute horlogerie and a globally recognized symbol of Jacob & Co watchmaking expertise. A world-first both in the boldness of its unprecedented concept and its entirely mechanical construction, the Astronomia has gone beyond impressive horological achievements and has been regarded as an outstanding multidisciplinary engineering achievement. Re-engineered from the ground up, the Astronomia Solar is the most compact in our peerless collection of Astronomia calibers.

The Astronomia Solar Zodiac recreates our Solar System, placed on the rotating platform of the Astronomia Solar caliber. Its three main arms carry the differential-driven time display, the magnesium globe in hand-painted blue lacquer for a spectacular representation of Planet Earth, and the one-minute flying tourbillon regulating organ, all rotating clockwise in ten minutes. Underneath, the aventurine base dial holds semi-precious stone plans, while turning counter-clockwise in 10 minutes.

The Astronomia Solar Zodiac makes for a beautifully artistic, highly refined and fully mechanical recreation of our solar system, to be appreciated like it has never been done before.

Exclusive Astronomia Caliber

The Exclusive JCAM19 caliber of the Astronomia Solar Zodiacstands out from an exquisite range of Astronomia calibers by being the most compact reiteration of the original, allowing for yet smaller case dimensions as well as redesigned proportions. Composed of 444 components, all finished to the highest standards of haute horlogerie, the Astronomia Solar Zodiac features two rotating platforms. One comprises the three main arms and subsidiary arms of the caliber, while the other is the aventurine Skylayer that serves as their spectacular, rotating backdrop.

The rotating platform of the JCAM19 caliber completes a rotation around the center of the watch in under 10 minutes, while simultaneously driving the aventurine Skylayer in a counterclockwise direction to add further animation and complexity to this unique take on celestial watchmaking.

The Astronomia Solar Zodiac brings a host of beautifully executed, astronomically inspired details to the world of Astronomia. The aventurine Skylayer disc rotates counterclockwise, holding half-spheres semi-precious stone planets.

The seven planets are represented by half spheres of semi-precious stones: White Granite for Mercury, Rhodonite for Venus, Red Jasper for Mars, Pietersite for Jupiter, Tiger Eye for Saturn, Blue Calcite for Uranus and Lapis Lazuli for Neptune.

Flying Tourbillon

Whereas the tourbillon was originally invented to be a single-axis, rotating cage secured from above as well as below to carry the regulating organ of a mechanical pocket watch for improved timekeeping performance, the Astronomia Solar Zodiac presents this 224-year-old invention in a yet more spectacular way.

The one-minute flying tourbillon of the Astronomia Solar Zodiac features a delicately decorated cage that encapsulates the balance wheel, hairspring, escape wheel and a number of other crucially important components. This openworked, rose gold cage not only features the J&Co logo in its architecture, but is only secured from underneath, allowing for an unobstructed and full view at the ultimate refinement of its detailing and operation. It is a constellation of superbly finished components that, when assembled and fine-tuned expertly, allows the JCAM19 to keep accurate time throughout its 48-hour power reserve.

Case & Crystal

The Astronomia Solar Zodiac's case measures 44 millimeters in diameter and 21 millimeters thick between the highest point of its specially curved front sapphire crystal and the lowest point of its case. Its case holds a single-piece sapphire crystal window around its periphery, allowing for unhindered viewing of the spectacular caliber and gemstones inside. One's focus on the universe that lives inside the Astronomia Solar Zodiac is further assisted by the openworked lugs - a minute, yet important detail that drives ones vision towards the center of the timepiece.

Dial & Hands

The time display sub-dial of the Astronomia Solar Zodiac is driven through an infinitesimal differential system that allows it to always remain in the correct 12/6 position and hence perfectly legible, even as the movement's platform performs its continuous, 10-minute orbit. The Zodiac symbols on the dial are hand-engraved and filled with 18K Rose Gold, while the hand-finished hands are plated with 18K Rose Gold.
