Here's my experience with a Rolex AD. November, 2018, walked into an AD not far from where I live (1st time btw), told the SA I was interested in the Milgauss Z-Blue. He took my information and called me the following month. I still have the Milgauss. In July of 2022, walked back into the same AD, asked for the new Sub 124060. The SA, different from the 1st, took my information and called me in January of this year with the Sub.
Maybe I'm just lucky.
My buddy just walked into a AD and purchased an Explorer I. No wait list or prior purchases with this AD and they had another one in stock they were trying to move and he said they also had a Yacht Master. Second hand prices on new Rolex's have also really come down. While these are not Subs or really super high demand models it seems to me that the inventory thing may be changing.
