Astronomia AT150.40.AC.SD.A is a horological spectacle that redefines the boundaries of traditional watchmaking, introduced in 2018 as part of the brand’s iconic Astronomia collection. Housed in a 50mm sapphire and 18k rose gold case, this timepiece offers a full panoramic view of its mesmerizing inner workings, protected by a domed sapphire crystal that wraps around the sides for uninterrupted visibility. At its heart is a gravitational triple-axis tourbillon, which rotates on three separate axes to counteract the effects of gravity, creating a ballet of constant motion.\u003c\/p\u003e \u003cp\u003eSurrounding the tourbillon are three additional arms mounted on a rotating carrier: a magnesium lacquered globe representing Earth, a rotating diamond-cut sphere symbolizing the moon, and a subdial for hours and minutes that remains upright thanks to an ingenious differential system. This timepiece is powered by both an automatic movement and the manual-winding JCAM10 caliber. The manual movement completes a full rotation every 20 minutes and offers a 60-hour power reserve. The Astronomia AT150.40.AC.SD.A is not just a timepiece—it’s a kinetic sculpture that fuses astronomy, fine watchmaking, and high jewelry into one unforgettable creation.\u003c\/p\u003e \u003cp\u003e\u003cmeta charset=\"UTF-8\"\u003e*The original retail price is $900,000 and this is a Piece Unique (1\/1).\u003cbr\u003e\u003c\/p\u003e","brand":"Jacob \u0026 Co.","offers":[{"title":"Default Title","offer_id":46517235646721,"sku":"P5761S","price":360000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1698\/0935\/files\/jacob-co-astronomia-at150-40-ac-sd-a-gravitational-triple-axis-automatic-tourbillon-piece-unique-2018-jacob-co-1154935480.jpg?v=1752206353","url":"https:\/\/goldennycjewelry.com\/products\/jacob-co-astronomia-at150-40-ac-sd-a-gravitational-triple-axis-automatic-tourbillon-piece-unique-2018","provider":"Golden NYC Jewelry and Watches Golden NYC Jewelry® | Fine Jewelry 18K Gold Watches Diamonds Gemstones","version":"1.0","type":"link"}
