Crafted from 18K rose gold with a single-block sapphire caseband, the 47 mm watch creates a transparent showcase around its constantly moving three-dimensional mechanism. The reference AT180.40.AB.UB.A is confirmed as the Opal configuration of the Astronomia Four-Axis Tourbillon. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eAt its heart is the hand-wound Jacob \u0026amp; Co JCAM54 caliber, composed of 485 components and engineered around a vertical rotating platform and flying triple-axis tourbillon.

The Opal edition is especially distinctive for its natural stone decoration, which gives each viewing angle a different visual character beneath the transparent sapphire architecture.\u003c\/p\u003e\n\u003cp\u003eUnlike a conventional tourbillon watch, the Astronomia Four-Axis produces movement across several planes simultaneously. The complete central platform rotates every 60 seconds while its flying triple-axis tourbillon performs three additional rotations. This complex mechanical choreography makes the AT180.40.AB.UB.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 case measuring 27 mm high, constructed from 18K rose gold and a single-block sapphire caseband.
