JACOB&CO. - ASTRONOMIA SKY
Jacob Arab, the founder of Jacobs, said: “As a sailor in the ocean to the sky vault, I found my star: Jacob & Co ASTRONOMIA SKY 750.110.40.AA.SD.1NS.” Just as humans are obsessed with the night sky from dawn. , Jacob & Co. Drawing inspiration from astronomical town clocks, these watches are a true masterpiece of technology and aesthetics.
The three-axis tourbillon turns to a 360-degree celestial sky panorama
In 2014, Jacobs and the company have already shocked the entire watch industry and launched the astronomical gravitational three-axis tourbillon watch. This year, Astronomia Sky is further challenged by adding unprecedented complexity: three-dimensional star display, oval sky indication and 24-hour day and night display. To understand the complexity of this feat, each innovation will be reviewed separately.
Stellar time
The celestial dial covers the inner surface of the Astronomia replica men watches case and completes a complete rotation within a stellar year - this is the actual time the Earth orbits the sun completely relative to the xed star. The blue 5-grade titanium dial is accented with 18K Venus, as well as applications and hand-carved and zodiac signs.
Oval sky indicator
Above the celestial dial is an oval sky indicator that shows the part of the star visible from the northern hemisphere. This indicator completes a complete rotation within one stellar day. The stellar day is the time it takes for the Earth to rotate once on its axis: 23.5640916 hours.
Day/night indicator
In the center of the satellite axis, a painted, hand-carved titanium sphere rotates inside a colored semi-dome sapphire, symbolizing day and night.
Satellite
Rotating around the watch are four satellite arms that rotate around the dial every 20 minutes, so when you replica watches swiss the watch, it never looks exactly the same. One of the satellites is the stunning three-axis gravity tourbillon, which rotates on one axis in 60 seconds, rotates on the second axis every few minutes, and rotates around the dial every 20 minutes.
The other satellite is a small dial of time (hours and minutes). Thanks to the clever differential system, the time display is always in the correct position when it is rotated around the dial. In other words, 12 is always in the up state. On the third satellite is the orbital seconds hand, an open titanium wheel that rotates with the second hand in 60 seconds, and it rotates around the dial every 20 minutes.
The fourth and final satellite is the patented "Jacob Cut" red moon, a spherical orange sapphire with 288 facets. This sapphire is the first sapphire in the modern jewellery industry, rotating once every 60 seconds on its axis and every 20 minutes.
Jacobs found a simple solution for this complex timepiece setup. In the astronomical sky there are two bows and two wheels on the back of the watch, making the setup easy. One bow is used to set the time and day/night indicators (both based on the 24-hour sun) and the other bow is used to wind the mechanical motion. One of the wheels sets the stellar time and the other wheel sets the elliptical sky indicator.
