If you’ve ever wondered when Jupiter will next be aligned with Mars, Van Cleef & Arpels has a watch that will tell you. Its new Midnight Planetarium Poetic Complication watch has six rotating disks, each bearing a tiny sphere representing one of the six planets visible with the naked eye.

The disks rotate at different speeds so that each sphere makes one revolution around the dial in the time it takes the actual planet it represents – Mercury, Venus, Earth, Mars, Jupiter or Saturn – to orbit the sun.  Mercury in 88 days, Venus in 224, Earth in a year, Mars in 687 days, Jupiter in 12 years and Saturn in 29. It’s a very complex watch and a true display of supreme watchmaking. Time is indicated by a shooting-star symbol rotating around the dial’s circumference. Leveraging the brand’s specialty in jewelry, each of the planets are represented by precious and semi-precious stones, ranging from red jasper to serpentine and turquoise. An even more extravagant edition is available with baguette-cut diamonds set into the bezel.

The planet module was designed by Christian van der Klaauw, renowned for his movements featuring astronomical indications. The movement is self-winding and contains 396 components.  The case is 44 mm in diameter and made of rose gold. The dial is made of aventurine and the planets of semiprecious stones.  Price: about $245,000; a diamond-set version will be about $330,000.
