Story

Feeling lucky?

In order to be truly exceptional, a timepiece must be about much more than just telling time. A case in point, acclaimed watchamking and jewelry house Jacob & Co.'s presents Astronomia Casino Baguette. It features a fully-operational miniature roulette wheel beneath the watch's sapphire crystal dome case. The Astronomia Casino Baguette's wheel, rendered in a spectacular array of green, red, and black enamel, is set in motion by a button at the eight o'clock position.

Thi particular version of the astronomia Casino is lavishly adorned with baguette-cut diamonds that cover the central part of the Roulette wheel, the lugs' front and flanks, and the entire bezel.

This exceptional timepiece, the most playful in Jacob & Co.'s signature Astronomia collection of celestial-themed timepieces, can be personalized with a mother of pearl insert placed by Jacob & Co. craftsmen on the owner's lucky number.

Double-Axis Tourbillon Movement

Whereas the tourbillon was originally invented to be a single-axis, rotating cage to carry the regulating organ of a mechanical pocket watch for improved timekeeping performance, the Astronomia Tourbillon brings this 224-year-old invention to breathtaking levels of modern refinement and complexity.

The double-axis tourbillon of the Astronomia Casino Baguette is at the forefront of modern watchmaking. The flying tourbillon's delicately decorated cage encapsulates the balance wheel, hairspring, escape wheel and a number of other crucially important components. Characterized by this open-worked cage, this outstanding tourbillon rotates on two axes simultaneously. It is a constellation of superbly finished components that, when assembled and fine-tuned expertly, allows the JCAM10 to keep accurate time throughout its 60-hour power reserve.

A full rotation on the 1st axis takes exactly 60 seconds, as a nod towards the traditional single-axis tourbillon. The 2nd axis of rotation is accomplished by the 10-minute rotation of the four-armed platform of the Astronomia Tourbillon. This makes for a bold new take on the tourbillon's core principled as engineered with cutting-edge, ultra-modern technologies and timeless horological heritage in mind.

ROULETTE TABLE ANIMATION

Never before has there been a grand complication timepiece with a roulette wheel that spins, allowing owners to play their favorite game of chance at any time. Though the Astronomia Casino Baguette is simple to use and enjoy, the technical solutions to actually make it work seamlessly took more than a year of development time.

Separated from the movement by a transparent sapphire crystal, the ceramic ball can bounce with abandon with no danger of impacting the functioning of the timepiece.

288-FACET JACOB-CUT DIAMOND

Located at the end of one of the four arms of the platform, a Jacob-Cut diamond starts out as a much larger rough precious stone. First, a rough diamond big enough has to be found, and its purity, clarity, and color have to be of the highest quality both inside and out. It can contain no inclusions. If the gem-cutters start to work on a diamond and find an inclusion, the entire piece will be ruined.

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

Then, the gem cutter shapes the stone by hand, cutting each of 288 individual facets. This has to be done slowly and carefully. 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.

THE MAGNESIUM GLOBE

Representing Earth, the globe is made of blue-lacquered magnesium with white gold continents. These materials ensure consistency in weight, between all four satellites, which must weigh exactly the same. The globe rotates on itself in 30 seconds, while travelling around the dial in 10 minutes with the platform.

CASE & CRYSTAL

The Astronomia Casino Baguette's case measures 47 millimeters in diameter and 24 millimeters thick at its highest. Crafted from 18K rose gold, the case features four sapphire crystal windows installed throughout the periphery, allowing for unhindered viewing of the spectacular double-axis tourbillon caliber and the functioning roulette wheel.

It is also set with a full row of baguette-cut diamonds on the bezel, two circular rows of baguette-cut diamonds inside the Roulette wheel. Its four lugs are set on the front and both sides with an array of diamonds, cut in order to occupy the entire surface of these fan-shaped components.

DIAL & HANDS

The time display sub-dial of the Astronomia Casino Baguette is driven through an infinitesimal differential system that allows it to always remain upright as it rotates along with the movement's four-armed platform. 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.
