Astronomia Sky Celestial Panorama in 18k rose gold was introduced in 2016 as a technical evolution of the original Astronomia. This reference features the manual-wind JCAM11 caliber, a gravitational triple-axis tourbillon that rotates the entire four-arm platform every twenty minutes. Collectors value this specific model for its celestial complications, including a sidereal display on a blue grade 5 titanium base dial and a vertical month indicator. The 47mm case utilizes a sapphire crystal monoblock construction to provide 360-degree visibility of the movement. Production is limited to 18 pieces globally. On the secondary market, this reference typically commands prices in the mid-to-high six-figure range, often between $450,000 and $600,000 depending on condition. A notable production detail is the inclusion of a 288-facet \"Jacob Cut\" orange sapphire that rotates on its own axis every 60 seconds."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": []}
