JACOB & CO. ASTRONOMIA SKY CELESTIAL PANORAMA TOURBILLON Jacob Arabo, founder of Jacob & Co, said: "As a sailor driven to the sea by the sky, I found my star: the astronomical sky." Fascinated by observation, Jacob & Co. draws inspiration from Astronomical Town Clocks, which are true masterpieces of technology and aesthetics.Jacob & Co. Astronomia Casino AT160.40.AA.AA.A Three-axis tourbillon goes to the stars In 2014, Jacob & Co shocked the watch industry with the launch of the astronomical gravity three-axis tourbillon. This year, Astronomia Sky takes the challenge a step further, adding an unprecedented complication: a three-dimensional star display combined with an elliptical sky indicator and a 24-hour day and night display. To understand the complexity of this feat, we'll examine each innovation individually. sidereal time The celestial dial covers the inner surface of the planetarium case and completes one full revolution in a sidereal year - the actual time it takes for Earth to make one full revolution around the sun relative to a fixed star. The blue grade 5 titanium dial features 18K gold stars and applied and hand-engraved zodiac signs. oval sky indicator Above this celestial dial is the oval sky indicator, which shows the portion of the star visible from the northern hemisphere. The indicator makes one full rotation in a sidereal day. A sidereal day is the time it takes for the Earth to rotate once around its axis: 23.5640916 hours.wholesale replica watches Day/Night Indicator At the center of the satellite axis, a painted, hand-engraved titanium sphere rotates within a tinted hemispherical sapphire, symbolizing day and night. satellite Rotating around the watch are four satellite arms that circle the dial every 20 minutes, so when you look at the watch it never looks exactly the same. On one of the satellites is the astonishing three-axis gravitational tourbillon, which rotates every 60 seconds on one axis, every 5 minutes on the second, and revolves around the dial every 20 minutes. On the other satellite is the time (hours and minutes) subdial. Thanks to an ingenious differential gear system, the time display is always in the correct position as it rotates around the dial, in other words, the 12 is always up.replica Grand Seiko Sport Watches On the third satellite is the orbital seconds hand, a skeletonized titanium wheel that rotates once in 60 seconds with the seconds hand, which also revolves around the dial every 20 minutes. On the fourth and final moon is the patented "Jacob Cut" Red Moon, a spherical orange sapphire with 288 facets. This sapphire, the first of its kind in the modern jewelry industry, rotates around its axis every 60 seconds and around the dial every 20 minutes. Optimize settings Jacob & Co. found a simple solution for the setting of this complicated timepiece. The Astronomia Sky has two bows and two wheels on the back for easy setup. One bow is used to set the time and day/night indicator (both based on 24-hour solar time), while the other bow is used to wind the mechanical movement. One of the wheels is used to set the sidereal hour and the other wheel is used to set the oval sky indicator. Known for their unique and captivating complications, Jacob & Co. has done it again with Astronomia Sky.replica Richard Mille for sale
