Why Should You Choose the Jacob & Co Astronomia Sky Black Gold in Dubai

The Jacob & Co Astronomia Sky Black Gold is designed for collectors who want more than a luxury watch—it offers a wearable representation of the universe. Its astronomical complications, continuously rotating movement, and striking black gold construction make it one of the most distinctive timepieces in the Jacob & Co collection. For collectors in Dubai seeking exclusivity, innovative engineering, and exceptional craftsmanship, this limited-edition masterpiece is an extraordinary addition to any high-end watch collection.

Design and Craftsmanship

The 47 mm case is crafted from luxurious 18K black gold and paired with a transparent single-block sapphire caseband that offers an uninterrupted view of the movement from every angle. Beneath the curved anti-reflective sapphire crystal, the openworked titanium hour and minute dial appears suspended above a blued titanium platform engraved with zodiac constellations and finished with elegant black gold inlays. The blued Jacob & Co. hands complement the celestial theme while ensuring clear readability without distracting from the spectacular rotating movement.

Movement and Performance

Powering the Astronomia Sky Black Gold is the hand-wound Jacob & Co. Caliber JCAM11, an advanced movement consisting of 395 components. Operating at 21,600 vibrations per hour, it delivers approximately 60 hours of power reserve while driving the signature vertical rotating central platform, which completes one full revolution every 20 minutes. The flying triple-axis tourbillon rotates on its first axis every 60 seconds and its second axis every five minutes, while the rotating 288-facet Jacob Cut® white diamond and orbital seconds each complete one rotation every 60 seconds. The movement also incorporates a central day and night indicator that rotates every 24 hours, a sidereal display that completes one revolution every 365.25 days, and a sidereal month indication, creating a fascinating mechanical interpretation of astronomical time.
