Why Is the Jacob & Co Astronomia Tourbillon Baguette a Dubai Collector’s Ultimate Diamond Tourbillon

Highly admired among Dubai luxury collectors for its unmatched mechanical complexity and diamond brilliance, the Astronomia Tourbillon Baguette elevates the iconic Astronomia concept into the world of ultra-high jewelry watchmaking.

Design and Craftsmanship

The watch features a 50 mm 18K rose gold case enhanced with 80 baguette-cut white diamonds on the lugs totaling approximately 6.10 carats and 40 baguette-cut white diamonds on the case band totaling approximately 3.03 carats. Beneath the unique domed anti-reflective sapphire crystal lies a rotating 18K rose gold base dial invisibly set with 257 baguette white diamonds totaling approximately 8.27 carats. The openworked titanium dial architecture allows uninterrupted visibility of the rotating Jacob-cut diamond, magnesium Earth globe, and triple-axis tourbillon. Every gemstone is meticulously hand-set to maximize brilliance and maintain seamless luxury finishing.

Movement and Performance

At the heart of the Astronomia Tourbillon Baguette lies the exclusive manual-winding Jacob & Co. Caliber JCAM40, composed of 339 components and 42 jewels. Operating at 21,600 vibrations per hour, the movement delivers approximately 35 hours of power reserve while powering a rotating four-arm vertical platform completing one full revolution every 5 minutes. The gravitational triple-axis tourbillon rotates on three independent axes: the first every 60 seconds, the second every 75 seconds, and the central axis every 5 minutes. The rotating Jacob-cut diamond and magnesium Earth globe each complete a full self-rotation every 15 seconds, creating continuous kinetic motion across the dial.
