Jacob Co. Astronomy Sky, Standard Time Jacob & Co. draws inspiration from the astronomical clock in history, which is a technological miracle. Known for its fascinating complication, the brand is back with astronomy Sky. It contains an unprecedented complication: a three-dimensional stereo screen, combined with an oval sky indicator and a 24-hour day and night display.
Jacob Arabo, the founder of Jacob & Co, said: "As a sailor, driven by the sky, I found my own star: the sky of astronomy." In 2014, he surprised the watchmaking industry with the launch of gravitational astronomy. The three-axis tourbillon.
The celestial body covers the inner surface of the astronomical box, achieving a complete rotation in the year of the star, which is the real-time time required for the earth to complete a complete rotation around the sun relative to a fixed star. Tier 5 blue titanium dial with 18K Venus and hand-engraved zodiac signs.
Above the celestial sphere is an oval-shaped sky indicator that shows a portion of the stars visible from the northern hemisphere. The indicator rotates completely on the stellar day. A stellar day is the time it takes the earth to rotate once on its axis: 23.5640916 hours.
On the satellite axis, a hand-carved, coated titanium globe rotates inside a semi-stained sapphire, symbolizing day and night. The blue bucket spins around the ball every 20 minutes. As a result, when people look at the clock, it never looks exactly the same.
The first satellite was a three-axis gravitational tourbillon, which revolved around one axis in 60 seconds, the second axis every 5 minutes, and the ball every 20 minutes. The second satellite is a sub-meter (hour and minute) of time. With the intelligent differential gear system, the time display is always in the correct position when rotating around the dial. The tag "12" is always looking.
On the third satellite is Orbital Second Hand, an open working titanium wheel that rotates the second hand for 60 seconds and orbits the ball every 20 minutes. The fourth and final satellite is the patented spherical gem "Jacob Cut", which has 288 cuts. The gemstone rotates around its axis every 60 seconds and around the ball every 20 minutes.
The astronomical starry sky has two arches and two wheels on the rear of the , which allows users to easily set the time. An arc is used to adjust the time and day / night indicator (both based on 24 hours of solar time), while another arc is used to wind the mechanical movement. One wheel is used to set the stellar time, and the other wheel is used to set the oval sky indicator.
