Why Is the Astronomia Tourbillon Black Gold a Must-Have for Luxury Watch Collectors in Dubai

The Jacob & Co Astronomia Tourbillon Black Gold is unlike any traditional luxury watch available in Dubai. Its revolutionary vertical movement, dramatic black gold case, and astronomical-inspired display create a mechanical experience that continuously evolves on the wrist. Combining an intricate triple-axis tourbillon with patented engineering and exceptional finishing, this limited-edition timepiece offers discerning collectors an iconic expression of innovation, rarity, and haute horlogerie.

Design and Craftsmanship

The 50 mm case is meticulously crafted from 18K black gold, creating a bold and contemporary appearance that perfectly complements the celestial inspiration of the Astronomia collection. A unique domed sapphire crystal with multiple anti-reflective treatments provides panoramic views of the rotating movement from every angle. The aventurine base dial resembles a starry universe, while the open titanium hour and minute dial appears to float above the rotating mechanism. Blued Jacob & Co. hands enhance readability while preserving the watch's dramatic architectural aesthetic.

Movement and Performance

Powering the Astronomia Tourbillon Black Gold is the exclusive hand-wound Jacob & Co. Caliber JCAM10. Built with 365 components and 42 jewels, the movement delivers approximately 60 hours of power reserve while operating at 21,600 vibrations per hour. Its revolutionary vertical architecture completes one full revolution around the central axis every 10 minutes. The gravitational triple-axis tourbillon rotates on three separate axes, completing rotations every 60 seconds, 2.5 minutes, and 10 minutes respectively. The patented differential gear system ensures the dial remains perfectly readable throughout the movement's continuous rotation, while the exclusive 288-facet Jacob Cut® diamond and magnesium blue lacquered globe each rotate independently every 30 seconds.
