Astronomia Sky AS900 in 18k rose gold was introduced in 2016 as a limited edition of 18 pieces. Collectors prioritize this reference for the JCAM11 caliber, a manual-wind movement featuring a triple-axis gravitational tourbillon, a rotating celestial vault, and a three-dimensional sidereal display. The 47mm case utilizes a sapphire crystal monoblock construction to provide visibility of the four-arm vertical movement, which includes a 288-facet Jacob-cut diamond and a magnesium globe. This reference marked a significant technical evolution for the brand by integrating astronomical complications with the rotating carousel architecture. On the secondary market, this model typically trades in the mid-to-high six-figure range, often between $400,000 and $600,000 depending on condition. A notable production detail is the celestial dial made of grade 5 titanium with 18k gold hand-engraved zodiac signs, which rotates once every sidereal year."}], "reviews": [{"slug": "jacob-co-astronomia-sky", "lang": "de", "title": "Jacob & Co.
