Jacob & Co. Astronomia Solar

The Jacob & Co. Astronomia Solar is the latest version of the Astronomical Tourbillon, one of the most talked about watches at Baselworld 2014. The Wall Street Journal’s Michael Clerizo called it one of his three favorite watch exhibitions, and that a company primarily known for its fine jewelry timepieces has created such a complex mechanism, and something visually spectacular, This leaves a lot of people dizzy and tongue wagging. Granted, this isn’t Jacob & Co.’s first high-end mechanical complication, but it’s certainly the most stunning from a design standpoint, and it’s certainly captured the collective imagination of the fashion watch world. A lot of companies love this truly otherworldly, minimalist, blazing watch design,

Since the launch of the first model, the design has continued to evolve. One of the most interesting models is Astronomia Sky, which includes a sidereal time indication and star map.

The latest version of Astronomia is Astronomia Solar. The Solar differs from other Astronomia watches in many ways. The first one you might notice is that the central carrier has three arms instead of four. The time is displayed on a dial (mounted on a differential gear system that ensures 12:00 is always on top to make the time easier to read), the tourbillon is on the second carrying arm; the globe representing the earth is on the third arm . The center of the carrier is a 1.5 carat citrine with 288 facets.

Bugatti Twin Turbo Black DLC

We’ll get to the planetarium later, but first there’s a piece created in collaboration with car brand Bugatti: the Bugatti Twin Turbo Black DLC. This is not the only collaboration between the two brands, as they offer, for example, the Bugatti Chiron tourbillon, which contains an animated miniature replica of the Chiron W16 engine, and there are many versions. But today, we’re interested in twin turbos.

This imposing piece gives us a grade 5 titanium case with a black PVD ​​​​finishing and a carbon fiber touch that still measures 57.3mm long, 51mm wide and 16.9mm thick. As you can understand, a real beast on the wrist is often the case with branded pieces, but here we’re at another level of inelegance.

It is the manufacture movement JCFM03 that brings this extraordinary timepiece to life. It contains 572 components and offers a decimal minute repeater complication, which means that at the push of a button, the watch will tell the time by displaying the hours, tens of minutes and minutes. Thus, the tens of minutes replaced the quarter-hours of the classic minute repeater. We can also observe the two hammers in action and part of the rest of the movement through the sapphire crystal on the caseback. It allows you to become aware of the quality and finesse of the finish, while indulging yourself in the crystalline sound of the multi-note cathedral bells.

In addition to this, the double triple-axis tourbillon at 6 o’clock on the dial ensures the high flying precision of this futuristic technological gem, while offering impressive visuals to take you on a journey into premium The world of watches and cars. The replica swiss watches is mounted on a black leather strap for a touch of elegance and classicism.

Jacob & Co. Twin Turbo Tourbillon

Jacob & Co. was founded in New York City in 1986, which means the famous watchmaker is now celebrating its 30th anniversary. They decided to do it in style, honoring 30 years of craftsmanship by presenting the Jacob & Co. Twin Turbo Twin Tourbillon.

This limited edition of only 18 pieces marks a milestone of innovation and excellence, while also embodying the brand’s characteristic sporty style. This new piece at Baselworld 2016 features the cathedral gong, offering a modern way to strike a bell.

Thus, the Jacob & Co. Twin Turbo Tourbillon marks the passage of time every 10 minutes.

Featuring a titanium and carbon fiber 57.3mm case, this extraordinary timepiece features a domed sapphire crystal, a sapphire display caseback, and is water-resistant to 30 meters. The Jacob & Co. Twin Turbo Twin Triple Axis Tourbillon is powered by a Swiss hand-wound Jacob & Co. caliber JCFM01 with 49 jewels, 21,600 vph and a 72-hour power reserve.

Complementing the overall youthful look, the dial features smoked sapphire sapphire with an applied logo, while a red Neoalithe inner ring adds a welcome pop of color. Now all that’s left is to hope that the black alligator strap with titanium unfolder will someday help you wear this wonderful statement. super replica watches

Opera Musical Watch by Jacob & Co.

Looking more like a work of art than an actual timepiece, Jacob & Co.’s latest creation has everything to take your breath away, from captivating designs to one-of-a-kind movements to musical surprises. Jacob & Co. Opera Musical is limited to 18 units, thanks to a beautiful 20-second melody that plays on 120 notes when the button at 2 o’clock is pressed, making your day even more exciting .

This may sound confusing, but the truly enthusiastic will realize that this unique feature is very close to true magic. The melody of this fascinating timepiece comes from the two music box cylinders on the dial, mounted on the specially developed hand-wound JCFM02 movement, which also features titanium components for ideal sound transmission.

The gorgeous 18kt rose gold touch continues to surprise, contrasting with the 47mm wide black DLC titanium case complemented by a sapphire crystal. The watch and its great music can even handle 30 meters of water, and the in-house movement, JCFM02, will be powered for 72 hours – it might just need them.

The finishing touch is the matte black lacquered dial, gold applied hour-markers and blued steel hands, although no one can take their attention away from that wonderful dial – if we may call it – or a music lesson, whatever How do you prefer. If you’ve ever wanted to wear music on your wrist, this is probably the best!

Jacob & Co. Bugatti Chiron Sapphire, as crazy and unique as a W16-powered supercar

One of the most impressive discount fake watch ever made just got even more luxurious.

Picture yourself waking up on a Sunday morning, getting out of bed, taking a shower, and starting the day in peace. You prepare yourself a nice espresso and a delicious breakfast. You check the time, kiss your partner goodbye, pick up the keys, and head to the garage to drive your new car. You open the door, sit on the leather seat, and enjoy a minute or two of silence. You check the time again, start the watch’s engine and turn the key to the ignition to energize the car. Two W16s run in perfect harmony, one on your wrist and one inches behind you, with 1,500 horsepower ready to propel you to the horizon. In case you were wondering, you wore a Jacob & Co. Bugatti Chiron sapphire crystal and fired up your Bugatti Chiron. And for seven lucky people, this dreamlike scenario is not far from reality.

Given that Bugatti will only be making 500 of the super-powerful Chirons, you’re more likely to encounter one of these than to find a Jacob & Co. Bugatti Chiron sapphire crystal in the wild. Only seven lucky men or women would love to own a watch like this; Jacob & Co. will only earn these. While it’s not the most restrained piece in watchmaking history, it’s certainly an impressive thing. The complexity of the miniature W16 automaton is a testament to the craftsmanship of the Jacob & Co. watchmakers. Like its Astronomia line, it’s a bold and expressive display.

Since the release of the first Jacob & Co. Bugatti Chiron Tourbillon, a few things have changed, and certainly this is the case most obviously. Now made in full sapphire crystal with anti-reflective coating, by the way, it measures a whopping 57.8mm in length, 44.4mm in width and 21.5mm in height. The case looks simple as it flows around the movement, but its shape is very delicately machined. Take a moment, curves and lines are everywhere, and of course the iconic Bugatti horseshoe grille at noon adds to the challenge.

The crown and pushers for starting the working sapphire crystal W16 engine are made of sapphire crystal and titanium. From left to right, we have the crown to set the time, the crown to wind the movement and the automaton, and the buttons to start the animation. The sapphire crystal engine is located in the lower half of the watch and has a miniature crankshaft milled from solid steel. This tiny crankshaft drives all 16 pistons up and down, just like in a real car.

While previously it didn’t have a dial of any kind, this version has a floating hour ring that helps make reading the time easier. Some elements of the watch, such as the hour indices, shock absorbers and tourbillon cage, are given a touch of red to match the red details on the exterior of the case. The power reserve indicator shows the French national colors on the left (Bugatti is located in Molheim, France).

Jacob & Co. fashion fully discloses the entire JCAM37 movement made in-house. While technically it’s the same movement as every Jacob & Co. Bugatti Chiron Tourbillon, it looks a little different here. For example, the bridges at the top of the movement have a different shape, as does the tourbillon cage (which now has a diamond on top). The power reserve indicator has also been given a new look, and the shape of the hands has changed a bit. The view on the back of the movement remains the same.

While evocative from the outside, the sophistication certainly matches the visual impact. The level of detail throughout the movement, chronograph face and automatic mechanism is haute horological. The hand-wound movement uses no less than 578 components, including 51 jewels. Suspending the movement with effective shock absorbers was a challenge for Jacob & Co. because you risked damaging the link to the fixed crown on impact. The solution is to use a patented car-style lateral system for a little gaming while keeping everything connected tidy. When fully wound through the left crown, the watch has a runtime of 60 hours. That’s far more than the 20 minutes it takes a Bugatti Chiron to empty the tank at full speed, mind you, plan your drive ahead of time.

In keeping with the swiss watch‘s supercar credentials, the Jacob & Co. Bugatti Chiron sapphire crystal watch is worn on a ventilated white rubber strap mounted on a titanium folding clasp.

Case: 57.8mm long x 44.4mm wide x 21.5mm high – full sapphire case, anti-reflective coating – sapphire crystal and titanium pushers and crown – Chiron “grid” with Bugatti logo on the strap at 12 o’clock Grid” – 30m waterproof
Dial: Red scale ring with red “EB” logo – Rhodium-plated hands with red tip – French red, white and blue power reserve indicator

Jacob & Co. The Godfather of the Opera – Mechanically

Music exists in time. Combining two traditional Swiss craftsmanship, Jacob & Co. Opera is both a highly complicated timepiece and a wearable music box…and, it’s an indescribable wrist performance. The ballet of its three-axis tourbillon and the musical mechanism in its operation is surprising and fascinating. Technically, the combination of these two rare complications is impressive. A lot really happens, if a picture is worth a thousand words, a video is worth a million…even a timepiece that defies conventional labels has to be shown, playing a godfather theme and featuring a miniature Don Vito Corleone of its center!

The music mechanism works by miniaturizing the music box to fit into the watch. It is powered by its own barrel. Like the minute repeater, the regulator flywheel controls the speed of the complication and sets the rhythm for the melody played by the gears driving two cylinders with pins and steel combs.

The 2 cylinders have manually set pins that sweep the 30 (2×15) blades of the 2 combs to play the melody. The precise adjustment of the pins and the different lengths of the blades produce different notes. Each of the 100 pins is hand-inserted into the cylinder with extreme precision. The manufacture of the comb is crucial, especially the length of the blade and its strength to produce the right melodies. exact replica watches

As the melody plays, the entire mechanical module – including the three-axis tourbillon, the musical mechanism and the off-centre hours and minutes display – rotates 120° around the dial in 20 seconds.

The JCFM02 hand-wound movement consists of no less than 664 parts and measures 43 mm in diameter. It is regulated by a three-axis tourbillon. The ballet of concentric cages allows for multi-dimensional rotation to counteract the negative effects of gravity: 40 seconds on the first axis, 3 minutes on the second axis, and 8 minutes on the third axis. The complex design contains 97 parts and weighs only 1.79 grams. Its variable inertia balance oscillates 21,600 times per hour. The power reserve of the chronograph mechanism is 72 hours.

Movement finishing involves a lot of work and artistic mastery. For example, the “Godfather” character at its center is hand-carved and hand-painted. The golden sheet music is hand-carved and painted. The cylinder is gold plated. The splints and bridges are sandblasted and PVD coated, and the screw heads are mirror polished. The dial is decorated with gold-tone appliqués with blued hands. replica watches review

This impressive movement is housed in a 47mm case made of DLC titanium and rose gold. It is protected by a highly domed sapphire crystal. The glass is made from just one part, a technical feat that, despite its curved top and clear cut angles, allows for unobstructed viewing of complex movements from all angles. The JCFM02 movement is wound and set via two folding crowns on the rear of the watch. The melody is activated via the pusher at 2 o’clock. The watch is worn on a crocodile leather strap, which is fastened with a folding clasp.

The Jacob & Co. Opera wasn’t the first musical watch, but with its striking design and ultra-complex mechanics (with a two-comb musical mechanism and a three-axis tourbillon), it was certainly at the top of its class By. It retails for CHF 300.000 for the “Godfather” DLC Titanium/Pink Gold Limited Edition we are reviewing. Several other versions are available for different materials, melodies and themes. A watch can also be ordered with a melody of your choice. jacob & co astronomia solar baguette as800.40.ap.yk.a

Jacob & Co. Astronomical Solar

This wholesale watch is tacky and cool. Of course you can also see the hours, but that’s secondary to me. I care about what’s going on around me. You have planets revolving around the surface, you have the universe in the background, and each planet has a different gem – which I love. The watch has a three-dimensional quality; it’s more of a fun mix of bracelet and watch. I also like the movement inside, you can see all the little pieces moving slowly. It’s like a Galileo thing to me. That’s what I saw when I saw this piece – an early intention to measure time.

Jacob & Co Astronomia Black Solar Zodiac Adds New Color to the Classic

The spinning solar system background builds on the already complex original.

Jacob & Co’s Astronomia Solar Zodiac has received its biggest design overhaul since the daring horological creation first launched in 2014.

Beneath a massive sapphire crystal dome, Astronomia Solar Zodiac Black features the design’s signature rotating three-armed turntable that serves as the base for a 60-second flying tourbillon, a 60-second rotating globe in rose gold and blue lacquer, and three other Hands – painted planets and self-orienting dial for hours and minutes. The entire assembly completes a clockwise rotation every 10 minutes.

But unlike previous versions (Conor McGregor recently showed off a brand new $1 million diamond-studded planetarium), here the backdrop is made of black aventurine glass and set with planets of the semi-precious solar system, which can also rotate, complete A 360 degree rotation in opposite directions at the same speed. fake men watches

At the center of the arrangement is a 2k Jacob cut yellow citrine whose 288 facets form an almost perfect sphere representing the sun.

The planets are composed of cabochon-cut semi-precious hemispheres: Mercury’s white granite, Venue’s ruby, Mars’ red jasper, Jupiter’s Peterstone, Saturn’s tiger’s eye and 18k rose gold ring, Uranus’ blue calcite and azure Lazuli, the gold stone, represents Neptune.

The impressive mechanism is housed in a 44mm black DLC-coated titanium case with a sapphire crystal aperture. Jacob & Co fake

Jacob & Co. Astronomia Casino Watch Hands-On

The Jacob & Co. Astronomia Casino, also known as the Jacob & Co. Astronomia Gambler, is another unique creation by Jacob & Co. conceived, designed and produced in a move towards their goal of dominating the field of absurd over-engineering Yet another, interesting, ultra-high-end watch — because such things do exist, and in fact have been for years.

Given that Harry Winston Opus watches dominated the mid-play naughty – widely and rightly considered the original source of haute horlogerie – creations that challenged the established limits of design and function – the early teens were all about Jaquet Droz Musical pieces, big brand complications with perpetual calendar, chronograph and striking mechanism. (A little basic research will make you realize how the value of these things from Audemars Piguet, IWC, Lange and others has fallen off a cliff, sometimes to 25% to 30% of the original retail price.) Why do I so? On the one hand, because I didn’t realize until recently that it was a common “serious complication” and not just a “disposable” lemon, and second, to show that there are so many people who can afford these things that are ready to hit their purchases (or even if they are not ready, they are forced,

Like it or not, the resale value of these once Holy Grail state watches is more than I can tell you about their current demand. Those who can burn six-figure sums (in dollars) when buying a watch have turned to watches that have any one or more of the following: 1) novel, 2) interesting, 3) expressive, 4) unique, 5) Simple appreciation. As with watches, the more boxes you tick, the higher the price in general. Jacob & Co. Astronomia Casino goes to great lengths to tick all those boxes, and then some.

With its – no other words to describe it – absurd thickness of 27.9mm (i.e. an inch, then some!), it’s a watch that’s easy to admire up close…and the other side of the dining table. It’s as discreet as a 1940s Francis Bacon pinned to your head while sitting at dinner, like a sail. Its weight is verified by the multi-layered, multipurpose JCAM29A movement, which includes the Astronomia “vertical movement” with its rotating platform consisting of four rotating arms and a fully functional, fully mechanical roulette complication beneath it .

First, a few words about astronomy. Although Jacob & Co. created many distinct variants of this movement, it is still excellent in terms of its construction and function. Powered by a single mainspring with an impressive power reserve of 60 hours (maybe longer or shorter depending on model variations and added complexity), essentially apart from the mainspring barrel and winding and setting “bow” Each component of the (crown replacement caseback) plays a role in this four-arm assembly.

Four arms with a double axis tourbillon (which I’ll explain shortly as a triple axis tourbillon), a blue magnesium miniature planet Earth, a 1 carat, 288 faceted Jacob cut diamond, which also goes around it Self-rotating shaft, and differential drive sub-dial for the time. These four arms rotate simultaneously on the face of the watch in less than 10 minutes – it is this rotation that adds a third 10-minute axis to the tourbillon.

The time display rotates with this assembly, so to prevent it from being upside down while running around the copy watch face, a differential is required. This allows the sub-dial to remain level, the hands to be driven, and the entire assembly to rotate together.

The tourbillon and rotating diamonds may be impressive, but two of my favorite astronomical achievements are this differentially actuated time display, and the fact that each two opposing arms are perfectly balanced against each other. Here’s some cool “invisible engineering” to keep the movement from being overly strained by the overweight arm that pulls or pushes the precision-running train assembly.

The heart of this astronomy is, of course, its roulette complexity. Press the button at the 8 o’clock position of the case, the roulette wheel is forcibly rotated, and the small white ceramic balls fly. To prevent it from entering the movement, the entire roulette function is set under a piece of sapphire crystal. The functionality of this complication is reassuring every time the button is pressed, and the overall execution of its every detail is as spectacular as it’s damned.

The wheels are made of 18k rose gold with black and red enamel for its 36+1 pockets. As I said, the thickness is 27.9mm, while the case diameter is 47mm. Oddly enough, with the lugs being so short and angled sharply downward, overall wear resistance is another way Astronomia Casino plays with the senses. Seen directly from above, the overall effect is manageable—even on my narrow wrist, which is 6.75 inches in diameter. However, once I start laying the watch flat away from myself, it starts to show off its crazy case construction, topped by a generously curved sapphire crystal. Speaking of which, the strap is a single sapphire crystal strap that, when paired with the skeletonized lugs, provides an easy view of the Jacob & Co. Astronomia casino in action.

As shown here, it is a one-of-a-kind piece. It’s certainly far more fun to play than any traditional grand complication, and even if one isn’t a gambler, the way this movement is constructed is sure to appeal to watch lovers inside.

Jacob & Co. Astronomia Tourbillon Watch

In 2014, Jacob & Co. best is back with an amazing timepiece sure to impress everyone from traditional watch lovers to the general public. Watching the video of the new astronomical tourbillon below, it’s easy to see why “wow” is the quintessential response to this complex and very interesting horological creation. When and if Astronomia will actually be produced is another question, but even if the timepiece is still a digital video, I’d be happy to create a pure concept.

The whole point of the Astronomia will give you the “four-arm” movement, it has a dial of the day (when the entire movement is rotated around its axis, it twists to keep it upright), the tourbillon (technically it’s at 2 pivot points), a rotating seconds indicator, and a rotating sphere inversion seconds indicator. Astronomia Sky more or less retains this performance (though designed and executed differently) and adds some astronomical complexity. Looking around the periphery of the dial through the face of the scene, you’ll see a small hand that follows with a 12-month scale that completely surrounds the face. Now, look at the center of this four-armed kinematic structure, and above it you’ll find a small sphere that looks like the Earth. This Earth sphere has a hemispherical shield that surrounds it to act as a day/night indicator. There are only two pivot points to note here, they are the 24-hour rotation of the day and night index and the fact that the earth rotates every 20 minutes, because that is the rotation time of the four-armed motion. The little “world” itself is made of titanium and then passes through Hand lacquered and engraved. The flow of this watch under motion is a celestial star chart with a zodiac indicator on it. The face is made of blued titanium (similar to the De Bethune watches we’ve long loved) and has an oval “sky indicator” hand. The entire dial actually rotates once a year,

Jacob & Co. was one of the first watch makers to understand the power of the “crazy watch”, a mechanical watch with epic complications simply meant to be stunning in a way similar to the tone and content of many rap music videos and impress. These are designed to be “ultra-luxury lifestyle” watches for those who buy a new yacht when they’re bored and browse eBay on their phone while waiting for their personal banker to leave the toilet of the yacht they’re currently sitting on. The only thing a watch like this makes sense, it should be more impressive than most other watches the wealthy can afford.

Nothing I said was mean or sarcastic. That’s really a rather small target demographic for a timepiece like this. We’re talking about that new money, a lot of new money. This type of consumer is interested in showing off their wealth because they sometimes don’t have the ability to spend it. Having said that, a piece like the astronomical tourbillon does carry an air of refined sophistication, as it has a high horological pedigree. While Jacob & Co. luxury may have a “diversified” customer base representing people you would and would not want to dine with, they certainly have the ability to get things done when they’re at it all.

Apart from videos and pictures, there is currently very little information on the astronomical tourbillon, and Jacob & Co. has prepared us well for the “launch” of this piece at Baselworld 2014. We hope to see it in person there or eventually. Sometimes a watch like this first debuts as a computer rendering, only to be actually released a few years later, because the time it takes to make a working movement can take much longer. This may be the case, as the astronomical tourbillon movement seems ambitious. While the watch itself isn’t astronomical complications, it’s themed around them. At the center of the watch is the “sun”, which is surrounded by four orbiting objects.

These items include a time dial (which remains upright in all positions as it moves around the main dial), a rotating representation of the Earth, a rotating spherical crystal (probably a diamond), and finally, an impressive Double-Axis Tourbillon. It’s all based on a beautiful planetary gear arrangement that any engineering student (or watchmaker) would be proud of as a semester project.

astronomia casino watch

It’s unclear if the spinning Earth is in line with the Earth’s 24-hour cycle and can be clearly used to indicate anything. It doesn’t even matter because its simple action looks fun. The dial at the time was probably the most impressive to me, as its visual presentation was both clear and distinctly complex.

Jacob & Co. presents the astronomical tourbillon in a large diameter 18k rose gold case, the bezel and crystal are made from a single piece of sapphire crystal. This allows a full view of the watch face from all angles. Also note that there is no crown, which means it’s either on the top of the watch, or more likely somewhere on the back. The mechanical movement itself is designed to represent only a small part of the dial to make the case more spacious and feel like the four “planets” have plenty of room to move. It is most likely hand-wound.

As a pure sport of horological decadence, the Astronomia Tourbillon is certainly a very interesting watch, and its production cost and final retail price may be just as awesome. We at love this stuff because it makes owning a simple timepiece a lot more fun. We can look at our basic “classic” watch and imagine that somewhere, someone might be wearing an astronomical tourbillon and reading it at the exact same time of day, but with more flamboyance.

A new astronomical timepiece from JACOB & CO.

This astronomical masterpiece from Popular Jacob & Co. is better than its predecessor (astronomy), but to fully understand this latest astronomical model, we must first understand its history. The first Astronomia version was used as a star map, accurately tracking the time and rotation of the Earth, as well as conditions around the Earth. It features hours, minutes, seconds, a tourbillon, and representations of the Earth and Moon rotating on spokes around a central axis (both visible under a broad sapphire dome). The Astronomia has sparked a wave of conservatism in its latest watch that has attracted many supporters of the Swiss watchmaking business, but it has also met some cynics because the watch is such an unconventional timepiece people.

Fortunately, perfect Jacob & Co. stopped most of the criticism with their new and improved Astronomia Sky. This timepiece includes a sidereal time display that follows the movement of the stars of the constellation. There has never been another watch as fascinating as the sidereal time complication, tried only on the most prestigious and complicated watches in history. According to Luca Soprana, founder and chairman of Jacob & Co., a watch development specialist unveiled in 2014, “Jacob Arabo’s idea was actually to create a kind of planetarium where all the stars and The planets are all moving around . . . ”

The Astronomia Sky‘s star map is located under an inverted dome above the movement, a roaming oval representing the stars above Geneva’s latitude. The dome gradually rotates at a rate of about 1 degree per day relative to Earth’s orbit around the sun, making a sidereal day (about 23 hours, 56 minutes, 4.1 seconds) different from a solar day. Luca Soprana said: “The great thing about working with Jacob is that he is not a watchmaker at all. He cares about the aesthetic quality of his work and asks for things that a technician would never ask for. He It required a completely different approach, and for me it was very interesting to work that way.”


American jewelry brand Jacob & Co has launched its latest Astronomia Flawless watch. Based on the unmistakably gravitational three-axis tourbillon watch, the timepiece features a sun, moon, globe and a complex movement, visible from all sides through a one-piece sapphire case. This gorgeous watch features sapphire barrel bridges in the movement, a blue sapphire dial, and a sapphire clasp on a blue strap.

The sapphire case of the Jacob & Co Astronomia Flawless watch consists of a case, a dome and a case back. Artisans take about 37 weeks to produce the sapphire components. To create the dome, master artisans cut the raw material, grind and machine it on CNC equipment, polish, finish ultrasonically clean and anti-reflection treatment. The case took 326 hours to complete, and an additional 300 hours of cutting, polishing, chamfering and brushing to complete the sapphire base. The sapphire disc that represents the dial takes 280 hours to make, and it takes about the same time to make the sapphire buckle.

At the heart of the Jacob & Co Astronomia Flawless watch is an upgraded hand-wound movement, the JCAM16 movement, with a three-axis tourbillon. The timepiece features two spherical, 288-faceted diamond spheres: one is a 1-carat Jacobean-cut diamond at one end of a satellite opposite an 18-carat rose gold and enamel globe. Between the two spheres, rising from the central axis of the movement, is a second diamond sphere – a 2.23-carat Jacobean-cut yellow diamond with facets.

Astronomical Sky at Jacobs & Co.

Jacob & Co.’s Astronomia Sky pushes the three-axis tourbillon even further.

For Jacob & Co, it has been making amazing complications the watch industry has never seen before (think Epic SF24, Quentin Tourbillon and Palatial Flying Tourbillon Jumping Hours and Minute Repeater), Astronomia 3-Axis Gravitational Tourbillon, in 2014 Launched, a game changer. Not only is it a unique complication, but it is a very beautiful watch.

This year, Jacob & Co. has taken the astrogravitational three-axis tourbillon completely to another level by adding a world-first astronomical complication.

The new Astronomia Sky introduces a three-dimensional star display, a unique day/night indication, an orbiting seconds hand, a gravitational three-axis tourbillon – of course – and a spherical orange sapphire moon.

This timepiece’s Celestial Dial is a blue grade 5 titanium dial featuring an 18-carat Venus and hand-engraved zodiac signs that make one full revolution every sidereal year – the actual time it takes Earth to make one revolution around the sun respects star.

Above this celestial dial is the oval sky indicator, which shows the portion of the stars visible from the northern hemisphere (don’t worry, Jacob & Co. will make one that shows the southern hemisphere sky as needed). The indicator makes one rotation in a sidereal day (23.5640916 hours).

Visible through the sapphire case opening, the 12 months are displayed on the side of the stellar dial. The perpetual calendar hands indicate the current date.

At the center of the satellite axis, a hand-engraved lacquered titanium sphere rotates on its own in a tinted half-dome sapphire crystal, symbolizing night and day. Due to the differential system, this Earth undergoes one full rotation in 24 hours a day. Replica Watches Store

Four satellites perpetual motion, revolving around the dial every 20 minutes. Rotating on one of the satellites is the stunning three-axis gravitational tourbillon, which rotates around one axis in 60 seconds; it revolves around the second axis every 5 minutes and the dial every 20 minutes.

On the other satellite is the time (hours and minutes) subdial. Thanks to the clever differential gear system, the time display is always in the correct position – in other words, 12 o’clock is always up!

On the third satellite is the orbital seconds hand, a skeletonized titanium wheel that rotates every 60 seconds, and it also makes one revolution around the dial every 20 minutes.

On the fourth and final moon is the “Jacob Cut Red Moon,” a spherical orange sapphire with 288 facets. A first for the modern jewelry industry, this gem cut rotates around its axis every 60 seconds and around the dial every 20 minutes.

Wow! Just describing the watch is challenging enough, imagine designing and producing it!
