Richard Mille’s signature timepiece for Pharrell Williams fell to earth this fall, hitting terra firma with a meteoric, nearly $1 million thump.

The model is the RM 52-05 Tourbillon. The watchmaking firm designed the wristwear for, and with the assistance of, Mr. Williams, who is an avid Star Trek fan and, presumably, a hobbyist watcher of the heavens. The timepiece is more jewelry than practical tool, however, favoring an extraordinary stylized rendering of space that’s part daydream and part expressionist painting.

The watch’s cosmetics are striking and compelling evidence of the Mille craftspeople’s talent. The material choices begin with titanium—a space travel-ready metal—and include rose gold, copper crystals, and a host of precious stones. The enameling and engraving used to express the dial represents many, many hours of work, and the watch’s mechanics boast 19 jewels, and offer a 42-hour reserve.

Production of the RM 52-05 Tourbillon is limited to 30 examples, and priced at $969,000.
