Pharrell Williams x Richard Mille RM 52-05 Watch, $969,000

Oh, OK, just a watch worth almost a mil. Some specs that might mean more to you than it does to us: The dial of the watch features an astronaut design where grade 5 titanium is met with white diamonds, black sapphires, 5N gold, and grand-feu enameling. It has manual winding tourbillon movement; the baseplate of the movement features large inserts in blue aventurine glass that evoke outer space. It also has a fast-rotating barrel, winding-barrel teeth, and third-wheel pinion with central involute profile (whatever that means).
