For the first time ever in watchmaking, and after more than a year in development, Jacob & Co. has incorporated two working derricks, an “oil” reservoir and a system of pipes into a timepiece, powered by a manual-wind double-axis tourbillon at its heart.

The tourbillon cage Oil Pump makes a full revolution on its first axis in 60 seconds and on its second axis in 2.5 minutes. The rose gold Oil Pump automaton is on demand, activated by a pusher at two o’clock.

All of this comes in a very wearable 47mm 18K rose gold and sapphire crystal case, with a solid 18K rose gold case back. Keeping the design clean, there is no setting crown, instead the winding and time setting is done using two bows built into the case back.

Everything is on display in the Oil Pump thanks to the unique domed sapphire with a double anti-reflective treatment. The watch is water resistant to 30 meters.

The Jacob & Co. Supernova Twin Central Tourbillons watch combines high watchmaking, a world first with two linked central triple axis tourbillons, with high jewelry, as the case is invisibly set with baguette hexagonal diamonds and the dial is set with hexagonal, “overlapping” diamonds.

The two mystery disks turn to indicate the time, rotating around the twin triple axis tourbillons, linked by a single differential, set into the center of the watch. This is a unique positioning, as most tourbillons are either set at the twelve or six o’clock position.

This is the first time that Jacob & Co. has placed its two incredible triple axis tourbillon movements in the center of the watch, where they turn on three axes: the first axis in 60 seconds, and the second and third axes in two minutes.

The minute disk is set with 119 White Diamonds (≈ 6.80 ct.) and one ruby (≈ 0.18ct.) to indicate the exact minute. The hour disk is also with 119 White Diamonds (≈ 7.93ct.) and one red ruby (≈ 0.28ct.) to show the hours. The 50mm 18K white gold case features a special domed sapphire crystal with anti-reflective treatment to show off the diamonds and the tourbillon, and the bezel inner ring is also set with gems — 12 Blue Sapphires (≈ 1.49ct.) and 108 White Diamonds (≈ 4.56ct.).

This year at Baselworld, Jacob & Co. introduced the Astronomia 3-D Setting, a new horological marvel boasting a setting technique inspired by the unique relief architecture of a building across the street from the Jacob & Co. boutique and offices in New York City.

Jacob Arabo, the founder of Jacob & Co. masterfully blends the intricate worlds of high jewelry and high watchmaking in the Astronomia 3-D Setting, introducing a new way to set and view beautiful, sparkling baguette diamonds.

The large sapphire crystal case has been a consistent design element of Jacob & Co.’s Astronomia collection since the introduction of the first Astronomia in 2014. The transparency of the case allows the movement of the gravitational triple axis tourbillon to be clearly visible from multiple angles. In the spirit of constant improvement, the Astronomia 3-D setting elevates the level of transparency with the use of the Astronomia’s distinctive sapphire crystal case.

The new 3-D setting adds relief to the aesthetic of the precious stones. On the 18K White Gold front case, 103 Blue Sapphires (≈3.36 ct.), 150 Icy Blue Sapphires (≈2.27 ct.) and 134 White Diamonds (≈3.31 ct.) are all 3D set by hand. On the lugs, 80 Baguette White Diamonds are invisibly set (≈6.10 ct.), also by hand.

At the heart of the Astronomia 3-D setting lies the superior timepiece craftsmanship for which Jacob & Co. is renowned. A triple axis tourbillon counteracts the effects of gravitation on the caliber’s mobile components as the tourbillon cage rotates in 60 seconds and completes a revolution over itself in 2.5 minutes, while the entire tourbillon covers a full revolution around the watch’s central axis in 10 minutes. Both the 1-carat, 288-facet Jacob Cut® diamond and the magnesium-lacquered blue globe rotate on themselves in 30 seconds, and travel with the tourbillon and the time display around the dial in 10 minutes.

Jacob & Co.’s patented Differential Gears System allows the time display to maintain the 12/6 o’clock position regardless of where it is in the rotation.

The Astronomia Flawless watch by Jacob & Co. continues to impress with its multifaceted meaning behind the new Astronomia’s name.

“Flawless” not only refers to the watch’s impeccable appearance, but it is also the term for the highest grade of diamond clarity according to the Gemological Institute of America’s diamond grading scale. For a diamond to be declared flawless, no inclusions or blemishes should be visible under 10x magnification. Flawless is therefore a fitting benchmark for Jacob & Co.’s evolutionary interpretation of the Astronomia collection’s signature sapphire case.

Jacob Arabo, the founder of Jacob & Co. masterfully blends the intricate worlds of high jewelry and high watchmaking in the Astronomia Flawless. In its new avatar in 2019, this horological masterpiece boasts a flawless 2.88 ct. diamond on top of the amazing Astronomia movement.

The large sapphire crystal case has been a consistent design element of Jacob & Co.’s Astronomia collection since the introduction of the first Astronomia in 2014. The transparency of the case allows the movement of the gravitational triple axis tourbillon to be clearly visible from multiple angles. In the spirit of constant improvement, the Astronomia Flawless elevates the level of transparency with the use of the Astronomia Flawless’s monoblock sapphire crystal case. The sophisticated craftsmanship of the monoblock sapphire crystal creates the illusion that the complications within the case are floating effortlessly in midair.

To achieve this appearance, a number of the collection’s components that were previously produced in precious metal are instead made in sapphire crystal. These changes have added a considerable layer of complexity to the new watch, as the production of the case middle alone requires 15 individual steps that account for around 326 hours of work, while the case back requires around 297 hours of work. Add to this the 288 hours required for the production of the domed crystal evident in all Astronomia models and you can see why this year’s Astronomia Flawless is a unique piece.

At the heart of the Astronomia Flawless lies the superior timepiece craftsmanship for which Jacob & Co. is renowned. A triple axis tourbillon counteracts the effects of gravitation on the caliber’s mobile components as the tourbillon cage rotates in 60 seconds and completes a revolution over itself in 2.5 minutes, while the entire tourbillon covers a full revolution around the watch’s central axis in 10 minutes.

Jacob & Co. expands upon its signature Astronomia Tourbillon collection with the launch of a customizable, casino-inspired model, the Astronomia Gambler.

Unveiled at the Baselworld International Watch and Jewellery Fair in March 2018, this grand complication timepiece also encapsulates a miniature roulette wheel beneath the watch’s sapphire crystal dome case. The dial of the Astronomia Gambler features all 37 squares of a roulette wheel, numbered from 0-36, in a spectacular array of green, red, and black enamel with mahogany inlays.

Creating a genuine casino experience, the owner of an Astronomia Gambler is given the opportunity to select his/her lucky number amongst the 37 squares. Jacob & Co.’s master craftsmen then place a mother of pearl insert on the chosen number slot. The Astronomia’s signature movement is set in motion by the automatic manufacture JCAA06 caliber whose rotor is none other than the roulette’s wheel.

Once the timepiece has been personalized, all that is left for the wearer to do is contemplate the roulette’s endless spinning, offering a reminder that life is a game of chance, and that one should try one’s luck until success is found. The Astronomia Gambler demonstrates Jacob & Co.’s unique ability to blend the highest level of the horological arts with bold, and playful design. The limited edition model offers only 18 pieces, each individually numbered.

This cutting-edge timepiece boasts not only an intricate and eye-catching design, but also a gravitational triple axis tourbillon; a staple within Jacob & Co.’s Astronomia collection. Although initially designed to counteract the effects of terrestrial gravitation on the caliber’s mobile components, the system gains in effectiveness by rotating on three axes: the cage housing the escapement goes around the balance wheel axis in 60 seconds and completes a revolution over itself in 2.5 minutes while the entire tourbillon covers a full cycle around the watch’s central axis in 10 minutes.

Regarding the timekeeping function, the timepiece boasts an off-center dial with the hours and minutes clearly legible in large-size Roman numerals and blue hand that stand out against the colorful backdrop.

Like the other versions in the collection, the Astronomia Gambler also houses an eye catching cosmic world under the glass dome where a lacquered magnesium terrestrial globe and an exceptional 288-facet Jacob-cut diamond, revolving around the dial in 10 minutes and over its axis in 30 seconds. The patented Jacob-cut diamond and magnesium blue lacquered globe adorn the roulette inspired timepiece like good luck charms.

Presented at Baselworld 2018, this new variation of its iconic Astronomia Tourbillon watch from Jacob & Co. offers a sleek and sophisticated take on the original design, housing its signature high-tech movements in case composed entirely of black ceramic. The pared-down setting immediately draws the eye to the watch’s four-armed vertical movements and further emphasizes the dramatic allure of the triple-axis gravitational tourbillon.

A spherical sculpture depicting Mars (rather than the Astronomia Tourbillon’s staple sculpture of the Earth) dances around the watch’s dial, which displays the hours and minutes. Accompanying the sculpture of Mars is a Jacob-cut rubellite, whose 288 facets sparkle like a fiery sun against the deep blue, star-studded aventurine background. Between the sculpture of mars, the Jacob-cut rubellite, and the red movement finishing, red accents reign supreme in the penumbra of the black ceramic case.

As with all the models within the Astronomia collection, the Astronomia Black Ceramic’s sapphire dome case protects the dial as though it were a precious jewel, while the transparent sides offer a clear view of the timepiece’s complex movements.

The Astronomia Black Ceramic’s refined aesthetic sheds new light on the artistry of its gravitational triple axis tourbillon. Although initially designed to counteract the effects of terrestrial gravitation on the caliber’s mobile components, the system gains in effectiveness by rotating on three axes: the cage housing the escapement goes around the balance wheel axis in 60 seconds and completes a revolution over itself in 2.5 minutes while the entire tourbillon covers a full cycle around the watch’s central axis in 10 minutes. The triple rotation ensures the extreme precision of the highly complicated timepiece.

Like a satellite following its trajectory in infinite space, the Astronomia Black Ceramic’s off-center dial, indicating the hours and minutes, rotates around the watch’s center axis in 10 minutes. Jacob & Co.’s exclusive JCAM24 caliber design, with its patented differential system, allows the dial to remain vertical throughout its revolution. The vertical positioning offers clear legibility of the time, which is further enhanced by the contrast of the watch’s rhodium-plated hands and red-accented Roman numerals.

The Astronomia Black Ceramic uses the capabilities of its exclusive movement to set a lacquered magnesium terrestrial planet and an exceptional 288-facet Jacob-cut rubellite in motion under its glass dome. The lacquered magnesium sculpture of Mars and Jacob-cut rubellite revolve around the tourbillon’s cage. The dial, indicating the hours and minutes, is also in perpetual motion, circling the watch’s face like a space station orbiting in a sidereal void.

Unveiled at Baselworld 2017, the Astronomia Solar wristwatch from Jacob & Co. displays eight planets of our solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

Made from 18 carat red gold, 44.5mm diameter case of the Astronomia Solar houses a movement of 34.55mm diameter and 439 components in constant bi-directional rotation and a representation of the solar system, enhancing even more the celestial reality.

The vertically built Jacob & Co. manufacture caliber JCAM19 has 3 arms. The first arm holds the hour & minute dial made of sapphire, it rotates counter-clockwise to ensure that 12 o’clock is always in the correct position, regardless of where the subdial is thanks to a patented differential system. The second arm holds two axes (10 min/60seconds) gravitational flying tourbillon decorated with a Jacob & Co. logo on its cage. The third arm holds an hand-engraved globe of the Earth rotating around its own axis in 60 seconds and completing one full revolution of the dial in 10 minutes.

The center of the movement is adorned with a Citrine Jacob cut® of approx. 1.5ct. The bi-directional movement rotates clockwise to complete a full 360 degree revolution in just ten minutes, the aventurine base rotates in the opposite direction at exactly the same speed, creating an accelerated, stylized view of the solar system.

The idea behind the Jacob & Co. Astronomia collection has always been to highlight, in a playful and suitably gem-set environment, the place of the Earth in our solar system.

In the Astronomia Solar, all eight planets in the solar system are given a place on the dial for the first time, with the sun at the center in the form of a 1.5ct Citrine with the unmistakable Jacob Cut® and its 288 facets.

The hand-engraved globe of the Earth rotates about its own axis once every 60 seconds and completes one full revolution of the dial in 10 minutes, as part of an assembly that also houses the subsidiary hour and minute dial and a one-minute flying tourbillon.

The reduced case size, new functions and faster rotation speed are all made possible by an entirely new in-house movement. The hand-wound Jacob & Co. calibre JCAM19 beats at a frequency of 4Hz (28,800 vibrations per hour), which is faster than any of the other Astronomia models. Yet in spite of its smaller diameter, at just 34.55mm, it actually comprises 439 components, excluding the precious and semi-precious stones, which is more than in the other Astronomia models.

Inspired from the complex nature and symmetrical composition of Octopus, Jacob & Co. has created a unique edition of its Astronomia model: the Astronomia Octopus, which houses a hand-crafted sculpture of an octopus through the Astronomia’s signature gravitational triple-axis tourbillon.

Taking into consideration both the sophistication of the design and the comfort of the wearer, the intricately handcrafted sculpture of the Octopus is composed of titanium. While titanium is ideal for adorning the movement without adding significant weight to the piece (the octopus weighs just 2.83 grams) the material is notoriously difficult to engrave or sculpt, making it all the more difficult to bring the piece to life.

In the typical manner of an octopus, the sculpture appears fully entwined in the JCAM16 manually wound caliber. Its tentacles wind around the Earth, the sun, the time and the triple-axis tourbillon. The central part of the movement, where the octopus is screwed to the central axis so that it may revolve around the dial like all the other components, is too modified from the Astronomia collection’s prior models to accommodate the new gold-plated sculpture.

The first Astronomia model to include a sculpture in the core of its composition, the Astronomia Octopus is displayed as a true work of art, cased in a new sapphire monoblock casing that allows the sculpture and complications to be admired from multiple angles. The entirely transparent monoblock case was originally created for the brand’s limited addition Astronomia Flawless. In both models, it creates the illusion that the complications inside the timepiece are suspended in mid-air, as the only non-sapphire elements are the two bows on the back to wind the movement and set the time.

The sapphire components of the Astronomia Octopus take a staggering 37 weeks to produce and each component requires at least a dozen different operations in its production. This excludes the time it takes to engrave the piece and the octopus sculpture, as well as the time allocated to assemble and meticulously hand-finish the movements.

Since its initial launch just under three years ago, Jacob & Co.’s Astronomia Tourbillon has consistently evolved with the introduction of each new model. Because of the additional layer of complexity added by the octopus, the Astronomia Octopus is piece-unique.

Jacob & Co. blends the intricate world of high jewelry with that of haute horlogerie to introduce the latest addition to the brand’s signature Astronomia collection, the Astronomia Flawless.

While the timepiece offers an exquisite display of immaculate aesthetics, there is multifaceted meaning behind the new Astronomia’s name. “Flawless” not only refers to the watch’s impeccable appearance, but it is also the term for the highest grade of diamond clarity according to the Gemological Institute of America’s diamond grading scale. For a diamond to be declared flawless, no inclusions or blemishes should be visible under 10x magnification. Flawless is therefore a fitting benchmark for Jacob & Co.’s evolutionary interpretation of the Astronomia collection’s signature sapphire case.

The large sapphire crystal has been a consistent design element of Jacob & Co.’s Astronomia collection since the introduction of the first Astronomia Tourbillon in 2014. The transparency of the case allows the movement of the gravitational triple axis tourbillon be clearly visible from multiple angles. Last year, Jacob & Co. increased the transparency of the case and the visibility of the Astronomia’s complications with the 2016 Baseworld novelty, the Astronomia Clarity. Nonetheless, in the spirit of constant improvement, the Astronomia Flawless again elevates the level of transparency offered by the Astronomia Clarity, with the introduction of the Astronomia Flawless’s monoblock sapphire crystal case. The sophisticated craftsmanship of the monoblock sapphire crystal creates the illusion that the complications within the case are floating effortlessly in midair.

To achieve this appearance, a number of the collection’s components that were previously produced in precious metal are instead made in sapphire crystal: the one-piece case middle and lugs, the dial (a blue-coloured sapphire) and even the buckle.

These changes have added a considerable layer of complexity to the new watch, as the production of the case middle alone requires 15 individual steps that account for around 326 hours of work, the case back requires around 297 hours of work, the dial 280 hours and the buckle 295 hours.  Due to long hours of work required in the production of each parts of this highly complex watch, for example its requires 37 weeks of production for just the sapphire components, only nine individually numbered pieces of the Astronomia Flawless will be made.

The manually wound JCAM16 caliber with its triple axis tourbillon, rotating earth and sun and subsidiary hour and minute dial has also evolved in the Astronomia Flawless. A rose-gold finish has been applied to the titanium bridges and the central axis is adorned with a 2.23-carat Jacob Cut® yellow diamonds representing the sun, in addition to the 1-carat diamond, which also has the 288 facets of the Jacob Cut®. Although the dial appears the same as on other Astronomia models, the dial on the Astronomia Flawless is actually made out of sapphire crystal and has been given a blue coating.

The Caviar Emerald embodies Jacob & Co.’s drive to stop at nothing in its quest to create masterpieces of incomparable beauty.

The 47mm hand-wound wristwatch represents the fruit of two years of tireless search for emeralds worthy of this ambitious project. Focused on finding emeralds of perfect dimensions and of a thrilling, radiant green, the watchmaker scoured the globe to assemble a collection of gems with perfect color homogeneity so as to accomplish its stunning final goal. The brand then took on the challenge, considered unachievable by conventional wisdom, of showcasing the emeralds with an invisible setting covering the entire timepiece. Achieved through 12 months of meticulous and delicate gem-setting artistry, the setting presents a sea of exquisite emeralds flowing into one another without a glimpse of human intervention, as if they were spreading naturally from the center of the dial before effortlessly enveloping the contours of the 18K white gold case.

Admired for millennia as symbols of love and eternal life, emeralds now adorn a timepiece befitting their unique resplendence. Surrounding an aperture in the dial through which the wearer is treated to a revelation of the JCBM05 caliber’s flying tourbillon, 140 baguette emeralds work as one to create an entrancing green hue of magnificent intensity. On the round case, 232 additional baguette emeralds, also invisibly set, extend the outward-spreading design and enrich the emanating effect, giving the impression that no structure even exists beneath them. A rose-cut emerald on the crown, framed by 16 additional gems, punctuates the exhibition of light and colour. Beneath the fabulous display beats a mechanical movement deserving of the masterful ornamentation.

The hand-wound caliber, which may be further admired through a sapphire crystal caseback, complements its one-minute flying tourbillon with a titanium balance, anti-shock system and 100-hour power reserve. Composed of 169 parts, the movement drives a two-hand dial display at a frequency of 21,600vph.

The strap’s tang buckle, in 18K white gold, completes the luxurious exhibition with an additional setting of 36 baguette emeralds. Created as a unique piece, the Emerald Caviar combines the apex of the jewelry arts and mechanical watchmaking in wearing its unforgettable beauty on the inside and outside alike.

The Brilliant Art Deco D-Flawless vividly combines Jacob & Co.’s two worlds of expertise to express the brand’s unique versatility and comprehensive mastery of the watchmaking arts.

Housed in a polished 47mm 18K white gold case invisibly set with 267 certified D-IF baguette diamonds, the timepiece’s open-worked architecture provides a superb view of the movement’s numerous hand-finished components and sculptural appeal. The D-Color Internally Flawless diamonds represent the highest caliber of quality. Their complete absence of internal flaws and extreme rarity make their abundance on the Brilliant Art Deco D-Flawless all the more remarkable.

The watch’s skeletonized design provides a delightful glimpse into the inner workings of the movement, allowing Jacob & Co. to symbolically illustrate its exceptional ability to fuse sumptuous jewelry and state-of-the-art horology. Set with 178 brilliant-cut Fancy Intense Pink diamonds (FIP), the JCAM04 caliber’s expressive bridges bring volume and a third dimension to the timepiece’s display.

Their luxurious adornments combine functionality and aesthetic beauty in a striking microcosm of haute horology. The play of light thus finds its way to the very heartbeat of the watch, and not merely to its elegant exterior. Such a riveting exhibition of the movement deserves a noteworthy level of mechanical complexity, and the Brilliant Art Deco D-Flawless does not disappoint. Conducting its 60-second revolution at 6 o’clock, the movement’s tourbillon demonstrates the technical talent and sophistication of Jacob & Co. The 21,600vph hand wound wristwatch indicates the hours and minutes with terrific precision and is further enhanced by a system of shock protection. Its three-day power reserve represents an impressive level of autonomy.

Echoing the internal flawlessness of the diamonds for which the timepiece is named, the caliber’s 150 components showcase the inimitable beauty of delicate craftsmanship and artisanal finishing. There values are further highlighted by hand-polished angles that contribute to the crisp aesthetic purity of the construction. A rose-cut diamond on the crown and 20 baguette diamonds on the alligator strap’s 18K white gold tang buckle complete the shimmering work of art.
