This is a video of the Panerai Radiomir PAM246 Foudroyante wristwatch, taken by PuristSPro. The foudroyante is one of the coolest types of watch complications. It measures 1/8th of a second with a dial numbered 1 through 8. The "foudroyante" hand completes a full rotation of the subdial every second, as you will see in this video.
