Jacob & Co. Astronomia Black Ceramic

Unveiled at Baselworld 2018, Jacob & Co.'s iconic Astronomia Tourbillon watch features a sleek, sophisticated original design that houses its signature high-tech movement in a case made entirely of black ceramic middle. The minimalist setting immediately draws attention to the vertical movement of the four arms of the watch and further emphasizes the dramatic appeal of the three-axis gravity tourbillon.

A spherical sculpture depicting Mars (instead of the main Earth sculpture of the astronomical tourbillon) dances around the watch dial showing the hours and minutes. Accompanying the Mars sculpture is a Jacob-cut rubellite, whose 288 facets sparkle with the fiery sun against a dark blue, star-studded aventurine backdrop. Between the Mars sculpture, the Jacobite-cut rubellite and the red movement finishes, the penumbra of the black ceramic case is dominated by red.replica watch Review

As with all models in the Astronomia collection, Astronomia Black Ceramic's sapphire domed case protects the dial as if it were a precious gemstone, while the transparent sides allow a view of the watch's complex movement.

The refined aesthetics of Astronomia Black Ceramic offer a new perspective on the artistry of its gravitational three-axis tourbillon. Although originally designed to counteract the effects of gravity on the moving parts of the movement, the system increases efficiency by rotating on three axes: the cage housing the escapement rotates around the balance axis in 60 seconds, and in 2.5 minutes It completes its rotation within 10 minutes and the entire tourbillon completes a complete cycle around the central axis of the watch. The triple rotation ensures the extreme precision of the highly complicated timepiece.Shopping replica watches

Like a satellite following its trajectory in infinite space, the off-centre dial of Astronomia Black Ceramic indicates the hours and minutes, rotating around the central axis of the watch in 10 minutes. Jacob & Co.'s exclusive JCAM24 movement design and its patented differential system keep the dial vertical throughout its rotation. Vertical positioning provides a clear and easy-to-read time, which is further enhanced by the contrast of the watch’s rhodium-plated hands and red Roman numerals.

Astronomia Black Ceramic harnesses the power of its exclusive movement to set a lacquered magnesium Earth planet and a remarkable 288-faceted Jacobite-cut rubellite under its glass dome. Mars and Jacob's lacquered magnesium sculpture of cut rubellite revolves around the tourbillon cage. The dial indicating the hours and minutes is also in constant motion, wrapping around the face of the watch like a space station orbiting in the stellar void.replica Chopard Imperiale Watch
