Astronomia Tourbillon Rose Gold AT100.40.AC.SD.A

Description of the Jacob & Co. Watch

The Jacob & Co Astronomia Tourbillon Rose Gold AT100.40.AC.SD.A is an iconic haute horlogerie masterpiece that revolutionized modern astronomical watchmaking through its breathtaking triple-axis tourbillon and rotating celestial architecture. Crafted in 18K rose gold with sapphire side apertures and a domed sapphire crystal, this extraordinary 50 mm timepiece transforms the universe into a fully animated mechanical sculpture featuring rotating planets, a Jacob-cut diamond, and a hand-painted Milky Way display.

How Does the Astronomia Tourbillon Rose Gold Combine Innovation and Craftsmanship

Highly celebrated among luxury collectors and haute horlogerie enthusiasts, the Astronomia Tourbillon is regarded as one of the most visually spectacular watches ever created. Its rotating celestial platform, animated triple-axis tourbillon, and gemstone planetary display create a mesmerizing cosmic experience unlike traditional watchmaking. Combining futuristic engineering with exceptional artisanal craftsmanship, the watch perfectly reflects an appetite for ultra-exclusive, theatrical, and mechanically groundbreaking luxury timepieces.

Design and Craftsmanship

The watch features a 50 mm 18K rose gold case enhanced with sapphire side apertures and a unique domed anti-reflective sapphire crystal that provides panoramic visibility of the movement. The aventurine base is hand-painted with the Milky Way and carries seven cabochon-cut gemstone planets representing the solar system, including white granite for Mercury, rhodonite for Venus, red jasper for Mars, pietersite for Jupiter, tiger eye for Saturn, blue calcite for Uranus, and lapis lazuli for Neptune. A rotating 288-facet Jacob-cut spherical diamond and a lacquered magnesium Earth globe further enhance the celestial aesthetic while showcasing Jacob & Co.’s exceptional gem-cutting and decorative artistry.

Movement and Performance

At the heart of the Astronomia Tourbillon Rose Gold lies the exclusive Jacob & Co. Manual Winding Caliber JCAM35, a spectacular mechanical movement composed of 617 components and 70 jewels. Operating at 21,600 vibrations per hour, the movement delivers approximately 60 hours of power reserve while powering a triple-axis tourbillon rotating across three independent axes. The first axis rotates every 60 seconds, the second every 2.5 minutes, and the third every 10 minutes as the entire chassis revolves around the dial. When fully wound, the movement activates a dynamic animation sequence during which the chassis completes four rapid rotations within approximately 15 seconds.
