Astronomia Four-Axis Tourbillon Labradorite AT180.40.AB.UD.A

Description of the Jacob & Co Astronomia Four-Axis Tourbillon Labradorite AT180.40.AB.UD.A The Jacob & Co Astronomia Four-Axis Tourbillon Labradorite AT180.40.AB.UD.A is an exceptional haute horlogerie timepiece combining Jacob & Co’s groundbreaking four-axis tourbillon architecture with the natural visual depth of labradorite. 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 & Co’s Astronomia Revolution Four Axis collection. At its heart is the hand-wound Jacob & Co JCAM54 caliber, a 485-component movement engineered around an ultra-fast rotating platform and flying triple-axis tourbillon. The combination produces four separate axes of motion, while a patented constant-force mechanism and differential-controlled orbital time display add further technical sophistication. Why the Jacob & Co Astronomia Four-Axis Tourbillon Appeals to Luxury Watch Collectors in the UAE For collectors in Dubai and across the UAE, the Jacob & Co Astronomia Four-Axis Tourbillon represents an extraordinary fusion of avant-garde Swiss watchmaking, rare decorative materials and mechanical artistry. The Labradorite edition stands apart through its natural stone base, whose characteristic variations and reflections provide a distinctive backdrop for the constantly moving mechanism. The 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 & Co describes the construction as its first four-axis tourbillon. Design and Craftsmanship The 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. A curved anti-reflective sapphire crystal creates a panoramic showcase around the vertical mechanical architecture. The labradorite base introduces natural texture beneath the mechanism, contrasting with the polished rose gold structures and transparent sapphire architecture. An off-centered skeletonized time display with applied rose gold-tone indexes and Dauphine-style hands travels around the central axis while remaining upright for easy reading. Movement and Performance Powering the watch is the Jacob & Co JCAM54, a hand-wound mechanical caliber consisting of 485 components. It operates at 21,600 vibrations per hour (3 Hz) and delivers approximately 36 hours of power reserve. The vertical central platform completes a full revolution every 60 seconds. At the end of one arm is the flying triple-axis tourbillon: its individual rotations occur every 60 seconds, 18 seconds and 15 seconds. Combined with the rotation of the complete platform, these movements create the watch's four-axis tourbillon architecture. A patented constant-force device manages the substantial energy required by this high-speed construction, refreshing its energy buffer every 1/6 of a second. On the opposite arm, a patented differential rotates the hours-and-minutes dial against the direction of the platform so that it remains upright throughout its orbit.
