Valued more for its complexity than its utility, a Rube Goldberg machine stuns onlookers with its thousands of whirring parts. Together, they create a chain reaction to perform a simple task—for instance, cracking open a fortune cookie or erasing a whiteboard.

Over the years, countless inventors have assembled their own Rube Goldberg machines. Now, Japanese watch company Seiko has followed suit, building what they bill as the world’s tiniest version of the contraption. According to Gizmodo, the mini-machine is fashioned from 1200 mechanical watch parts—some smaller than 1 millimeter in size. Not surprisingly, its end goal is to add a final part to a newly made Seiko watch.

Nerdist reports that Seiko filmed the small Rube Goldberg machine for an advertisement, which they titled “Art of Time.” Watch it in action in the video above.
