I have ordered a bunch of Rolex within the last months
and they all will be delivered til 2022 (or even have been delivered): 5 steel (2 SD, 2 Sub, SkyD), 1 two-tone GMT, 1 plat DD, 1 everose YM
The AD even offered me other wg daytonas that I did not pick cause I have them already.
Even when the windows are only stacked for display / not for sale, I at least have made the experience that they get deliveries and sell them to customers like me who don't sell them again. In my understanding they want to control the flow to the grey market thus not selling to anyone they don't know or whom they have not heard about. "We want to keep the watches here locally".
