Astronomia Tourbillon is a luxury watch from Jacob & Co.

In 2016, Jacob & Co. launched Astronomia, a revolutionary timepiece of unheard-of complication and proportions. In a 47mm case made of gold with a sapphire baseband, a vertical, rotating movement is set up whose satellite carriage bears four arms. One is a twin-axis tourbillon, another is a rotating dial fitted with a differential to keep it upright, one is a 288-facet Jacob-cut diamond representing the moon, and the fourth is a magnesium earth globe.

All four arms are in rotation around their own axis and around the central axis as they orbit inside the case in 20 minutes. This, incidentally, creates a third rotation axis for the tourbillon carriage. Astronomia has no crown, no central hands, and nothing in common with any other usual timepiece.
