Wow...some great pics guys. The zenith and GO immediately came to mind when I read the title. Those Blancpains are nice too.
On a more affordable level, Ive always liked Alpina's black rotor with its guillotine shape.
Also the skeletonized rotor on the Nomos Neomatik movements. Not sure why more manufacturers dont opt for a skeletonized rotor. Even ETA or Sellita...its high-time they make a standard rotor thats skeletonized. Just looks cooler!
