How Does the Jacob & Co Astronomia Sky Titanium Redefine Luxury Watchmaking

Its transparent architecture offers an uninterrupted view of the constantly rotating movement, while its remarkable celestial displays transform the watch into a miniature mechanical universe.

Design and Craftsmanship

The 47 mm case is crafted from lightweight titanium and paired with a transparent single-block sapphire caseband that offers spectacular visibility of the movement. Protected by a curved anti-reflective sapphire crystal, the openworked blue Grade titanium hour and minute dial appears suspended above a titanium platform engraved with zodiac constellations and enhanced by elegant black gold inlays. Blued Jacob & Co. hands provide excellent readability while complementing the contemporary aesthetic and celestial design of the Astronomia collection.

Movement and Performance

At the heart of this extraordinary watch 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 signature vertical rotating central platform, which completes one 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. Additional astronomical complications include 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 faithfully tracks celestial cycles.
