Jacob & Co. Astronomia Gambler watch AT150.40.RO.SD.A price



 replica Jacob & Co. Astronomia Sky is a watch made by luxury watch brand Jacob & Co.

“Astronomy is a very, very delicate work. Every component needs to be perfectly balanced, so we need to use very special materials – like titanium – which are very delicate. The real idea is to create a 3D look The watch, and the watch has to be spectacular.”

Manufactured in a specification described as 18ct yellow gold, this 3D Tri-Axis Tourbillon Watch features an oval sky indicator with a sidereal display and celestial panorama. Gravity three-axis tourbillon, day/night indicator, hour and minute sub-dial and orbital seconds, "Jacob Cut" red moon orange sapphire, 288 faces.swiss luxury replica watches

The celestial dial covers the inner surface of the Astronomia's case, and it completes one full revolution in a sidereal year - the actual time it takes Earth to complete 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.

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.Jacob & Co. Astronomia Sky 750.110.40.AA.SD.1NS

At the center of the satellite axis, a painted, hand-engraved titanium sphere rotates within a tinted semicircular sapphire, symbolizing night and day.

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 a three-axis gravitational tourbillon, which rotates every 60 seconds on one axis, every five 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.wholesale replica watches

On the third satellite is the orbital seconds hand, a skeletonised titanium wheel with a seconds hand that also makes one revolution around the dial every 20 minutes every 60 seconds. On the fourth and final satellite is the patented "Jacob Cut" red moon, a spherical orange sapphire with 288 facets. The sapphire, the first of its kind in the modern jewelry industry, rotates on its axis every 60 seconds and around the dial every 20 minutes.

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. moon-watch.co
