OK, here are more questions:
Is the box for the Red Sub always supposed to be the seahorse box? Or can it be the coffin box as well?

I wonder where the price limit for vintage Rolexes will be? Or will there be any pricelimit at all?

I used to have a really nice 25xxx serial red sub someone stole from me, and that one had a perfect unrefinished dial. So I should settle for no less than a completely original untouched dial.
