When I decided to buy my Tudor BB36, I was told there was a 6 months waiting list plus the 3 months I intended to pay it off on layaway. The watch came in for me about a week after being put on the waiting list and I paid it off within another few weeks. So, my intended 9 month wait lasted only a few weeks. I have no idea if the waiting list was real or not.
I dislike polished centre links myself, which is why I chose the No Date Sub instead (and recently flipped a Christopher Ward C60 beater which also had PCLs. After one year, I realised I just didn't like them). They're both beautiful watches, though.
