Astronomia Solar Full Baguette

Astronomia Solar Full Baguette

Story

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 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.

Despite its close-packed design, the Astronomia Solar Full Baguette features the precious center of our Solar System as a Jacob-Cut®, 288-facet gemstone sphere, placed on the rotating platform of the Astronomia Solar caliber. Its three main arms carry the differential-driven, self-leveling time display, the magnesium globe in hand-painted blue for a spectacular representation of Planet Earth, and the one-minute flying tourbillon regulating organ.

The Astronomia Solar makes for a beautifully artistic, highly refined and fully mechanical recreation of our solar system, whereas its Full Baguette version replaces some of those celestial bodies with the breathtaking beauty of precious stones.

Exclusive Astronomia Caliber

The Exclusive JCAM19 caliber of the Astronomia Solar Full Baguette stands 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 447 components, all finished to the highest standards of haute horlogerie, the Astronomia Solar Full Baguette features two rotating platforms. One comprises the three main arms of the caliber, while the other is the 18K Rose Gold Skylayer set with 144 baguette-cut white diamonds.

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

BAGUETTE LUGS

The lugs of the 18K rose gold and sapphire-case are invisibly hand-set with baguette-cut white diamonds.

Astronomia Solar Full Baguette Skylayer

Rotating Gemstone Planet Display & Diamond-Set Skylayer

The Astronomia Solar Full Baguette brings a host of beautifully executed, astronomically inspired details to the world of Astronomia. A view on our home planet can be experienced by a hand-painted blue globe, crafted from lightweight magnesium. A yellow sapphire shaped with the exclusive Jacob-Cut® and its 288 facets complement the cutting-edge watchmaking feats of the Astronomia Solar Full Baguette. Serving as a spectacular backdrop for these displays is the Skylayer disc that is invisibly set with 238 diamonds, all rotating counterclockwise - against the rotation of the Astronomia's three-arm movement platform. This makes for a unique coming together of gem-setting prowess and ultra-high-end watchmaking, as can only ever be experienced in a Jacob & Co creation.

Astronomoia Solar Full Baguette Flying Tourbillon

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 Full Baguette presents this 224-year-old invention in a yet more spectacular way.

The one-minute flying tourbillon of the Astronomia Solar Full Baguette 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.

Astronomia Solar Full Baguette Case & Crystal

Case & Crystal

The clean, yet powerful lines of the Astronomia Solar Full Baguette's case are further amplified by 144 baguette-cut white diamonds, tracing the uniquely complex lug and case profile, and highlighting their hollowed-out structure. The case measures 44.5 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 18K Rose Gold 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 Full Baguette is further assisted by the openworked lugs - a minute, yet important detail that drives ones vision towards the center of the timepiece.

Astronomia Solar Full Baguette Dial & Hands

Dial & Hands

The time display sub-dial of the Astronomia Solar Full Baguette is driven through an infinitesimal differential system that allows it to always remain levelled and hence perfectly legible, even as the movement's four-armed platform performs its continuous, 10-minute orbit. 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.

At A GLANCE:

The Jacob & Co. flying tourbillon, time display, and hand-painted magnesium globe and three 288-facet Jacob-cut gemstones make one full revolution of the dial in 10 minutes, rotating clockwise

The Sun is represented by a yellow 288-facet Jacob-cut Sapphire (≈ 1.5 cts)

The dial holding the eight planets makes one revolution counter-clockwise, in 10 minutes

This base dial is invisibly-set with baguette white diamonds

The lugs of the 18K rose gold and sapphire-case are invisibly hand-set with baguette-cut white diamonds.

The eight 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 Saturn and Lapis Lazuli for Neptune

With the upper assembly turning clockwise in 10 minutes and the diamond-set base holding the planets turning clockwise in 10 minutes, the Astronomia Solar Zodiac never looks the same way twice
