Astrographic Movement Question

[movintage]

Hi everyone. I'm a new member who has always admired vintage Zodiacs. I've been collecting watches, vintage & modern  for about 10+ years but haven't pulled the trigger on a Zodiac, yet.

I've been adding Mystery Dial watches to my collection and want an Astrographic SST. I saw this for sale at what I believe is a fair price but not sure if the movement is genuine. All Zodiac movt I've seen have signed rotors, this doesn't? Can the experts here take a look and let me know your opinions.

Thanks,
Movintage

Yes, it has been replaced. Should say Zodiac and the caliber is 88.

Thank you Butch.   
Can you tell if the rest of the movt  is genuine with just the rotor having been replaced?

[Butch]

Sorry, I cannot.
