Jacob & Co. Astronomy Sky Celestial Body Panoramic Gravity Three-axis Tourbillon Watch At Baselworld 2016 (Baselworld 2016), Jacob & Co. launched a new and fascinating astronomical giant watch called Jacob & Co. Astronomical celestial panoramic gravity three Axis tourbillon. “Jacob & Co. Astronomia Sky” is not intended as a replacement, but as a complement to the original Jacob & Co. Astronomia, adding some complexity and actually having a smaller case.
The size of Jacob & Co. Astronomia Sky is only 50 mm wide for standard astronomy, while the “width” is only 47 mm and the thickness is 25 mm. No one will be slim because of such a watch, because it is slim, but Jacob & Co. was asked to make a more wearable watch for its interesting astronomers.
Please also note that our Jacob & Co. Astronomical celestial panoramic gravitational three-axis tourbillon image is a pre-production prototype. One of the most critical missing elements in this prototype watch is the lack of anti-reflective coating on the sapphire crystal. This makes the readability quite poor, and it is almost impossible to photograph the details of the watch through the crystal. Suffice it to mention, because the “final” version of the watch will not have these dazzling crystal issues.
The first appearance of the Jacob & Co. Astronomical Observatory Panoramic Gravity Three-axis Tourbillon Watch uses an 18k rose gold case with a large domed sapphire crystal on the top and a middle sapphire crystal ring on the side of the case. It makes viewing the inside and movement of the watch very simple and attractive. And, yes, there is a pen that can be used together. Well, in fact, these pens are used as a whole with the astronomy series of watches. They are produced by Visconti in Italy in cooperation with Jacob & Co. These are also pre-production prototypes, and they will be in 18k rose gold and 18 white gold.
The whole gist of astronomy is to provide a “four-arm” movement with a time dial (as the entire movement structure rotates on its axis, it rotates to keep it upright), a tourbillon (technically in two Move on the pivot point), rotating the second hand indicator and the rotating ball opposite to the second hand. Jacob & Co. Astronomy’s Sky more or less retains this feature (although the style and execution are different) and adds some astronomical complexity.
If you look around the dial from the side of the case, you will see a monthly indicator that uses a small hand to follow the 12-month scale of the entire dial. Now, look at the center of the four-arm motion structure. On top of it, you will find a small sphere designed to look like the earth. The earth ball has a hemispherical band around it to act as a day/night indicator. Pay attention to the two pivot points here. They are the 24-hour rotation of the day/night indicator and the fact that the earth rotates every 20 minutes, because this is the rotation time of the four-arm movement. The small “ball” itself is made of titanium, then painted and carved by hand. replica watches review
There is a celestial star chart with a series of zodiac indicators on the dial below the movement. This face is made of blue titanium (similar to what we have long loved in De Bethune watches) and has an oval “sky indicator” hand. The entire dial actually rotates once a year, and the oval sky indicator hand rotates once every sidereal day (approximately one day) to show the stars visible in the northern hemisphere.
As you can see, Jacob & Co. wants to add a lot of astronomical information to its astronomy watch. I think they did a good job in Jacob & Co. Astronomia Sky, but actually made the watch smaller. Of course, the watch is still a serious “display product”, most of its value lies in the design and exquisite performance of the exquisite mechanical device.
Compared with the original astronomy, the movement design of the Jacob&Co. Astronomy celestial panoramic gravity three-axis tourbillon has changed. The “Jacob cut” diamond is replaced here with a rotating “Jacob cut” orange sapphire, which rotates once per minute and is shaped like a sphere with 288 facets. Opposite the Jacob Cut sapphire crystal is the second hand, which is intended to match some wavy structures that together represent an orbiting satellite.
The movement inside the watch is unique to the Jacob & Co (reproduced by Studio7h38) movement JCAM11. The hand-wound movement is made of 395 parts, the operating frequency is 3Hz (21,600bph), and the power reserve is 60 hours. The movement is fascinating with its complexity and focuses on visual entertainment in operation.
Jacob & Co. Astronomia Sky combines 18k rose gold and blue (with a matching crocodile leather strap), looks exceptionally magnificent. This time, there are no diamonds on Jacob & Co., but if I know Mr. Arabo, there will be diamonds on Jacob & Co. Astronomia Sky in the future. Like most watches produced by the brand, Astronomy Sky by Jacobs Ltd. is part of a limited edition.
I can’t wait to see the final version with the right sapphire crystal, because I think this and the entire astronomical watch series are some of the most interesting “outside” watches. These watches are obviously very luxurious, but not the kind of fake luxury watches we immediately assume Looks best on oligarchs. I can see the astronomy starry sky of Jacob’s company on the wrist of a successful kind ruler!
