Jacob & Co Celestial astronomy Sky Panorama Panorama Gravity Triple Axis Tourbillon

Jacob Arabo, the founder of Jacob & Co, said: “As a sailor, driven by the sky to the ocean, I found my star: the astronomical sky.” Just like the fascination of mankind with the night sky since the dawn of Jacob The company (Jacob & Co.) is inspired by astronomical timepieces, which are true technical and aesthetic masterpieces.

Three-axis tourbillon turns into stars
In 2014, Jacob & Co launched the Astronomia Gravitational three-axis tourbillon, which shocked the watch industry. This year, by adding unprecedented complications, the sky challenge of astronomy is even more severe: three-dimensional display, oval sky indicator and 24-hour day and night display. To understand the complexity of this feat, each innovation will be examined individually.

Sidereal time
The astronomical dial covers the inner surface of the astronomer’s case and completes a complete rotation in one year of stars-this is the actual time it takes for the earth to revolve around the sun relative to a fixed star. The blue 5-grade titanium dial is equipped with 18K gold stars and is affixed with hand-engraved zodiac signs.

Oval sky indicator
Above the celestial disc is an elliptical sky indicator, which shows some of the stars visible from the northern hemisphere. The indicator rotates a full circle in a sidereal day. The sidereal day is the time it takes for the earth to make one revolution: 23.5640916 hours.

Day/night indicator
In the center of the satellite axis, a titanium globe with a hand-painted lacquer surface rotates inside the colored hemispherical sapphire, symbolizing day and night.

Rotating around the watch are four satellite arms, which rotate around the dial every 20 minutes, so when you look at the swiss men watch, its appearance will never be exactly the same.

On one of the satellites is an amazing three-axis gravity tourbillon, which spins on one axis in 60 seconds, on the second axis every ve minutes, and rotates around the turntable every 20 minutes.

On the other satellite is the time (hour and minute) sub-dial. Thanks to the clever differential gear system, the time display always rotates around the dial and is always in the correct position, in other words, the 12 always stays up.

On the third satellite is Orbital Second Hand, which is a hollow titanium wheel with a second hand that can rotate for 60 seconds and also rotates around the dial every 20 minutes.

The fourth and final artificial satellite is the patented “Jacob Cut” red moon, which is a spherical orange sapphire with 288 facets. This sapphire is the first in the modern jewelry industry, rotating around its axis every 60 seconds and the dial every 20 minutes.

Optimize settings
Jacob & Co. luxury found a simple way to solve this complicated timepiece setting problem. There are two bows and two wheels on the back of the astronomical star watch to make setting up easy. One bow is used to set the time and day/night indicator (both are based on 24 hours of solar time), while the other bow is used to wind the mechanical movement. One wheel is used to set the sidereal time, and the other wheel is used to set the oval sky indicator.

Jacob & Co., known for its unique and fascinating complications, did it again with the astronomy Sky.
