Jacob Arabo, better known as Jacob The Jeweler, was once the go-to jewelry for a number of celebrities and hip-hop stars. This week, he returns with his latest creation: the Astronomia Tourbillon.

The timepiece originally debuted at Baselworld in 2013. It measures at 50mm in diameter and sits 25mm high, thanks to its domed sapphire crystal. An openworked dial inside features a four-armed carrier that hosts a triple-axis tourbillon and motion works.

On the two arms, one carries an enamel-decorated globe representing the Earth, and the other, a 288-facet, one carat diamond representing the moon. Both rotate once per minute while the tourbillon itself rotates once every 60 seconds, 5 minutes and 20 minutes.

The Astronomia Tourbillon is finished in 18k rose gold and featuring a 60-hour power reserve and is water-resistance up to 30 meters. Finally, it’s limited to just 18 pieces and available now via Jacob & Co.
