Why Is the Jacob & Co Astronomia Sky Black Titanium the Best Choice for Collectors in Dubai

The Jacob & Co Astronomia Sky Black Titanium is designed for collectors who appreciate advanced engineering wrapped in a bold, contemporary design. Its lightweight titanium construction, transparent sapphire architecture, and astronomical complications distinguish it from traditional haute horlogerie timepieces. With only six examples produced worldwide, this exclusive model offers luxury watch enthusiasts in Dubai an opportunity to own one of Jacob & Co.'s rarest and most innovative creations.

Design and Craftsmanship

The 47 mm case is crafted from black titanium and paired with a transparent single-block sapphire caseband that provides uninterrupted views of the spectacular movement. The openworked blue Grade titanium hour and minute dial appears suspended above a blued titanium platform engraved with zodiac constellations and enhanced with elegant black gold inlays. Protected by a curved anti-reflective sapphire crystal, the movement is showcased from every angle, while the blued Jacob & Co. hands maintain excellent readability without distracting from the celestial display.

Movement and Performance

Powering the Astronomia Sky Black Titanium is the hand-wound Jacob & Co. Caliber JCAM11, an advanced movement composed of 395 components. Operating at 21,600 vibrations per hour, it delivers approximately 60 hours of power reserve while driving the 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, 1-carat Jacob Cut® white diamond and orbital seconds each complete one full rotation every 60 seconds. Completing the celestial display are a central day and night indicator rotating every 24 hours, a sidereal display completing one revolution every 365.25 days, and a sidereal month indication that accurately follows astronomical cycles.
