Crafted from 18K rose gold and surrounded by transparent sapphire architecture, the 47 mm watch showcases its three-dimensional movement from virtually every angle.\u003c\/p\u003e\n\u003cp\u003eThe Hematite reference AT180.40.AB.UE.A belongs to Jacob \u0026amp; Co’s Astronomia Revolution Four Axis collection, one of the brand’s most technically ambitious interpretations of the Astronomia concept. The model combines an ultra-fast rotating platform, a flying triple-axis tourbillon, constant-force regulation and an orbital hours-and-minutes display. The reference is confirmed in Jacob \u0026amp; Co's current catalog. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eWhy the Jacob \u0026amp; Co Astronomia Four-Axis Tourbillon Appeals to Luxury Watch Collectors in the UAE\u003c\/h3\u003e\n\u003cp\u003eFor collectors in Dubai and across the UAE, the Jacob \u0026amp; Co Astronomia Four-Axis Tourbillon represents a remarkable fusion of avant-garde Swiss watchmaking, precious materials and mechanical artistry. The Hematite edition is particularly distinctive because its dark natural-stone base provides a dramatic contrast to the warm rose gold construction and transparent sapphire case architecture.\u003c\/p\u003e\n\u003cp\u003eUnlike a conventional tourbillon watch, the Astronomia Four-Axis creates movement across multiple planes. The complete central mechanism revolves around the watch while the flying triple-axis tourbillon simultaneously rotates through three additional axes. This constantly changing architecture makes the AT180.40.AB.UE.A particularly appealing to collectors seeking rare Jacob \u0026amp; Co watches and exceptional high-end timepieces in the UAE. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch4\u003eDesign and Craftsmanship\u003c\/h4\u003e\n\u003cp\u003eThe Astronomia Four-Axis Tourbillon features a substantial 47 mm 18K rose gold case surrounded by a single-block sapphire caseband.
