Astronomia Four Axis Tourbillon Rose Gold

Description of the Jacob & Co. Watch

The Jacob & Co Astronomia Four Axis Tourbillon Rose Gold AT180.40.AB.AA.A is a groundbreaking haute horlogerie masterpiece that pushes the limits of mechanical engineering through the world’s first four-axis tourbillon. Crafted in 18K rose gold and sapphire crystal, this extraordinary timepiece combines ultra-fast rotational mechanics, a constantly rotating movement platform, and futuristic architectural design into one of the most technically ambitious creations ever produced by Jacob & Co.

What Makes the Astronomia Four Axis Tourbillon Rose Gold So Exclusive Among Luxury Watches

Highly admired among elite luxury watch collectors, the Astronomia Four Axis Tourbillon represents the pinnacle of avant-garde watchmaking and kinetic artistry. Designed to celebrate the 10th anniversary of the Astronomia collection, the watch introduces the world’s first quadruple-axis flying tourbillon while maintaining the signature rotating Astronomia architecture. Its mesmerizing movement rotations, sapphire case visibility, and sculptural rose gold construction create a dramatic visual spectacle that perfectly aligns with an appetite for ultra-exclusive haute horlogerie innovation.

Design and Craftsmanship

The watch features a massive 47 mm 18K rose gold and sapphire crystal case with a highly domed anti-reflective sapphire crystal that offers panoramic visibility of the rotating movement. The mirror-polished rose gold mosaic backplate reflects light dynamically as the platform rotates, creating a constantly changing visual experience. Unlike traditional Astronomia models, this version utilizes a two-arm platform to reduce weight and maximize rotational speed. The displaced red composite time display remains upright at all times through a patented differential system, highlighting Jacob & Co.’s exceptional technical creativity and finishing expertise.

Movement and Performance

At the heart of the Astronomia Four Axis Tourbillon lies the Jacob & Co. Caliber JCAM54, a hand-wound mechanical movement composed of 485 components. The movement platform completes one full revolution every 60 seconds, making it the fastest rotating Astronomia movement ever created. Positioned on the platform is the revolutionary four-axis flying tourbillon, whose axes rotate in 60 seconds, 18 seconds, 15 seconds, and 60 seconds respectively. A patented constant-force mechanism regulates the immense energy flow generated by these ultra-fast rotations while preserving chronometric precision. The movement delivers approximately 36 hours of power reserve.
