The Jacob & Co. Astronomia Solar Jewelry Planets Zodiac Black DLC Titanium (AS310.21.SP.AA.A) is a limited edition timepiece that artfully replicates our solar system. Its three rotating arms display the time, a hand-painted globe representing Earth, and a one-minute flying tourbillon, all revolving in a 10-minute cycle. The aventurine base dial rotates counter-clockwise, carrying seven planets made of cabochon-cut precious stones. The watch features a blue PVD dial with rose gold-plated engravings of zodiac signs, housed in a 44mm black DLC titanium case with sapphire apertures. It is powered by the exclusive Jacob & Co. manual winding JCAM19 movement, offering a 48-hour power reserve. The timepiece is completed with a blue alligator leather strap and a black PVD titanium deployment buckle.
