How Does the Jacob & Co Astronomia Revolution Black Gold Redefine Luxury Watchmaking in Dubai

The Jacob & Co Astronomia Revolution Black Gold is designed for collectors who demand groundbreaking engineering rather than conventional complications. Unlike traditional Astronomia models, its entire movement revolves once every minute, creating an unmatched visual spectacle powered by an advanced constant force mechanism. Limited to just six pieces worldwide, this remarkable watch offers Dubai's luxury collectors an exceptionally rare opportunity to own one of Jacob & Co.'s most technically ambitious timepieces.

Design and Craftsmanship

The 47 mm case is crafted from 18K black gold and paired with a transparent single-block sapphire caseband that showcases the movement from every angle. Beneath the curved anti-reflective sapphire crystal, the black spinel base creates dramatic depth, while the skeletonized black polycarbonate subdial with applied 5N gold indices provides a modern architectural appearance. Elegant 5N red gold dauphine hands ensure excellent readability, complemented by a distinctive steel arrow seconds indicator tipped with a pyramid-shaped synthetic ruby.

Movement and Performance

Powering this exceptional creation is the hand-wound Jacob & Co. Caliber JCAM48B, an advanced mechanical movement composed of 434 components. Operating at 21,600 vibrations per hour, it delivers approximately 30 hours of power reserve while driving the revolutionary vertical rotating platform, which completes a full revolution every 60 seconds. The flying double-axis tourbillon rotates on its first axis every 60 seconds and on its second axis every 15 seconds, while the innovative constant force device reloads six times per second to maintain consistent energy delivery. Completing the visual spectacle is a rotating seconds hand that moves counterclockwise every 15 seconds.
