Talked to the saleswoman while I got a link added to my Tudor today. The Rolex counter was empty except for a Cellini and a couple of women's watches. I figured they were hiding some in the back. Nope, that's all they had. She said they could order Datejust and President, but that was it, and it was a month-plus wait for those. Anything else they got was whatever Rolex felt like sending, and it sold almost right away. You could get on a waiting list, but there were no promises on when you'd get what you wanted.
She also said that Rolex no longer shipped parts. Everything had to go to Rolex, and if they deemed anything on your watch not a genuine Rolex part, they wouldn't work on your watch. Interesting conversation.
