[url=رابط][b]Jacob & Co ASTRONOMIA SKY[/b][/url] JACOB & CO. Astronomical Sky, Sidereal Time Jacob & Co. draws inspiration from historic chronometers, timepieces that are technical marvels. Known for its fascinating complications, the brand returns with the Astronomia Sky. It incorporates a complication never seen before: a three-dimensional star display combined with an oval sky indicator and a 24-hour day/night display. "Like a sailor sailing out to sea, guided by the firmament, I found my star: the sky of Astronomia," said Jacob Arabo, founder of Jacob & Co. In 2014, he Introduced the Astronomia Gravitational Triple Axis Tourbillon.[url=رابط][b]luxury cheap watches[/b][/url] The astronomical dial covering the inner surface of the astronomical watch box completes one rotation in one sidereal year, which is the actual time for the earth to revolve around the sun relative to the stars. The grade 5 blue titanium dial features 18K gold stars and hand-engraved zodiac signs. Above the celestial sphere is the oval sky indicator, which shows the portion of the stars visible from the northern hemisphere. The indicator completes one rotation in one sidereal day. A sidereal day is the time it takes the Earth to rotate once: 23.5640916 hours.[url=رابط][b]replica watches wholesale[/b][/url] At the center of the satellite axis, a hand-carved lacquered titanium sphere rotates itself within a semi-dome of colored sapphire, symbolizing day and night. The blue barrel rotates around the sphere every 20 minutes. So when people look at a watch, it never looks quite the same. On the first satellite is the three-axis gravity tourbillon, which rotates every 60 seconds on one axis, every 5 minutes on the second axis, and rotates around the dial every 20 minutes. On the second satellite are the time subdials (hours and minutes). Thanks to an ingenious differential gear system, the time display is always in the correct position as it rotates around the dial. The "12" mark is always facing up.[url=رابط/gmt-sport-c-202_463.html][b]Replica Greubel Forsey GMT Watch[/b][/url] The third satellite is the Orbital Second Hand, a skeletonized titanium wheel that circles the dial every 20 minutes and the seconds hand every 60 seconds. The fourth and final satellite is the patented "Jacob Cut" spherical gemstone, featuring a 288-faceted Jacob cut. The jewel rotates on its own axis every 60 seconds and orbits the sphere every 20 minutes. The back of the Astronomia Sky has two arcs and two wheels, which make it very easy for users to set the time. One bow is used to set the time and day/night indicators (both based on 24-hour solar time), while the other is used to wind the mechanical movement. One of the wheels is used to set sidereal time, while the other is used to set the oval sky indicator. movement Manual, JCAM11 movement, 395 components, 42 jewels, 60 hours of movement Function Oval Sky Indication, Day/Night, Month, Triaxial Gravity Tourbillon, Second Track Indication, Hours and Minutes, Patented Differential Case Rose gold size 47mm crocodile [url=رابط][b]replica luxury watches[/b][/url] [url=رابط][b]replica watches for sale[/b][/url] [url=رابط/patek-philippe-watches-c-78.html][b]replica Patek Philippe watches[/b][/url] [img]رابط/images/Jacob%20Co%20Astronomia%20SKY%20watch%20AT110-30AA-WDA.jpg[/img]
