Astronomia Art Dragon reference AT802.30.DR.UA.A is a piece-unique or highly limited production model introduced around 2018 as part of the Astronomia Art collection. Collectors value this reference for its JCAM25 manual-wind caliber, a gravitational triple-axis tourbillon featuring a four-arm movement that rotates every ten minutes. The 50mm 18k white gold case features monoblock sapphire crystal side windows to display a hand-engraved 18k rose gold dragon that weaves through the movement components. This specific execution includes a 288-facet Jacob-cut diamond and a magnesium globe. On the secondary market, these pieces typically command prices in the mid-to-high six-figure range, often between $600,000 and $800,000 depending on provenance. A notable production detail is that while the movement is standardized, the hand-painted dragon sculpture requires over three months of dedicated engraving and finishing, ensuring no two examples are identical.", "score": 200}]}
