Astronomical Sky by Jacob & Co A model with a stunning starry panorama and a three-axis tourbillon. jacob and co astronomia replica

Jacob Arabo, founder of Jacob & Co, said: "Like a sailor in the sea, looking up at the sky, I found my star, which is Astronomia Sky."

In 2014, the brand introduced the Astronomia Tourbillon with a three-axis tourbillon [cf. About her in our forum here. self]. This year, it was decided to add a three-dimensional sidereal hour indicator to the chronometer series, alongside a star map and a day/night indicator.
The Astronomia Sky dial is made in the form of a firmament that makes one revolution at intervals equal to a sidereal year (a sidereal year is the time it takes for the Earth to make a complete revolution around the sun relative to the star). In fact, the "sky" itself is made of grade 5 blue titanium and, for the sake of completeness, is adorned with 18-carat white gold stars and hand-engraved zodiac signs. There is an indicator directly below the dial, which is a map of the northern hemisphere starry sky. This sub-dial makes one revolution in an interval equal to one sidereal day (one revolution of the Earth on its own axis takes approximately 23.560916 hours).Replica moon watches

The dial is enclosed by a glass hemisphere below which the four-axis modular design can be seen in detail. At the center of the structure is a hand-carved painted titanium sphere. Protected by a tinted sapphire crystal dome, the ball rotates on its own axis, symbolizing the change of day and night. Ball Spin Speed ​​- 1 full revolution every 20 minutes.

The modular structure itself rotates at the same speed, with a three-axis tourbillon at one end. The speed of rotation of the tourbillon along the different axes is as follows: 60 seconds around the first axis, 5 minutes around the second axis, and 20 minutes around the third axis.

The upper part of this cosmic combination is occupied by a subdial with hour and minute indications. Thanks to the differential system, the hour index is always positioned vertically, which makes it possible to read exactly the clockwise hour readings that the user is accustomed to. The third Earth “satellite” in the unusual watch collection is the orbital seconds hand – a skeletonised titanium wheel that makes one revolution around its axis in 60 seconds. The fourth companion is the orange “Jacob Cut” sapphire, which shines with 288 facets, also making one revolution around its axis in 60 seconds and around the dial in 20 minutes each.

This micromechanical marvel can be controlled via a special ring mounted on the back of the watch. The first ring is used to set the time and day/night indicator, and the second ring is used to operate the mechanism. You can adjust sidereal time and correct the appearance of the star map using the gear, which is also on the back of the model.

The in-house hand-wound calibre JCAM11 is responsible for the coordination of all the functions of this watch. The 40mm-diameter movement consists of 395 titanium parts mounted on 42 jewels and runs at a balance frequency of 21,600 A/h with a power reserve of 60 hours.

The Astronomia Sky case is made of 18K rose gold and has a diameter of 47mm. On the front, the case is closed with a domed sapphire crystal. The case back is also made of rose gold. The case is water resistant to 30 meters.

It is recommended to wear the High Quality Replica watches on an alligator leather strap with a rose gold folding clasp.
