Jacob & Co. Astronomia Tourbillon

This year, Jacob & Co.—masters at haute joaillerie watches—once again surprises and delights with a huge array of timepieces that range from complex tourbillons to stunning emerald delights. Last year, the brand released its Astronomia watch; this year, there are several new renditions—in an updated format that brings the Earth and moon to all new heights.

The new Astronomia watch has been reconfigured with a larger, more open-aired, domed sapphire crystal for viewing the sun, moon, and tourbillon with multi axes. The newest pieces: Astronomia Baguette and Aventurine. Both are powered by the JCEM01 caliber with an orbital display that makes a full cycle around the dial every 20 minutes thanks to four individual satellites. The moon is created using a 288-facet spherical diamond that reflects incoming light in a multitude of directions throughout its 60-second rotation around an independent axis. The handprinted titanium Earth sphere also rotates every 60 seconds. The tourbillon orbits the dial, alongside the other objects, every 20 minutes and a fourth arm offers the hours and minutes display.
