Crafted from 18K rose gold with a single-block sapphire caseband, the 47 mm watch surrounds its three-dimensional mechanical construction with transparent sapphire, allowing the rotating movement to be viewed from multiple angles. The reference AT180.40.AB.UD.A is confirmed within Jacob \u0026amp; Co’s Astronomia Revolution Four Axis collection. \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, a 485-component movement engineered around an ultra-fast rotating platform and flying triple-axis tourbillon.

The Labradorite edition stands apart through its natural stone base, whose characteristic variations and reflections provide a distinctive backdrop for the constantly moving mechanism.\u003c\/p\u003e\n\u003cp\u003eThe Astronomia Four-Axis is particularly remarkable because the entire movement participates in the tourbillon architecture. A central carousel completes one revolution every 60 seconds while a flying triple-axis tourbillon mounted at the end of one arm rotates through additional planes at extremely high speeds. Jacob \u0026amp; Co describes the construction as its first four-axis tourbillon. \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.
