Why Is the Jacob & Co Astronomia Tourbillon Clarity Rose Gold a Favorite in Dubai

The Jacob & Co Astronomia Tourbillon Clarity Rose Gold offers one of the clearest views of the brand's revolutionary Astronomia movement thanks to its sapphire crystal construction. Every rotating component is visible from virtually every angle, allowing collectors to fully appreciate the complexity of the triple-axis tourbillon and the spectacular vertical movement. For luxury watch enthusiasts in Dubai seeking exceptional exclusivity and innovative Swiss craftsmanship, this limited-edition masterpiece is an outstanding addition to any prestigious collection.

Design and Craftsmanship

The 50 mm case combines luxurious 18K rose gold with transparent sapphire crystal to create a breathtaking three-dimensional display. Jacob & Co.'s signature domed sapphire crystal features multiple anti-reflective treatments, maximizing visibility of every moving component. The off-centered titanium dial with blued Jacob & Co. hands floats elegantly within the movement, while the rotating 288-facet Jacob Cut® diamond and blue lacquered magnesium globe continuously enhance the watch's visual depth. A sapphire caseback with rose gold metallisation completes the sophisticated transparent design.

Movement and Performance

At the heart of this extraordinary timepiece is the exclusive manual-winding Jacob & Co. Caliber JCAM24, comprising 365 meticulously hand-finished components and 42 jewels. Operating at 21,600 vibrations per hour (3 Hz), it delivers a 60-hour power reserve while powering the iconic Astronomia display. The vertical four-arm movement completes one full revolution every 10 minutes, while the gravitational triple-axis tourbillon rotates every 60 seconds on its first axis, every 2.5 minutes on its second axis, and every 10 minutes on its central axis. A patented differential gear system ensures the off-centered hours and minutes dial remains perfectly oriented throughout its continuous rotation.
