You prob don't want to hear this but in reality you want one of the hottest watches on the planet and have no relationship. Therefore you have literally zero chance unless you buy a load of unwanted items from an AD (which will end up being more expensive then simply buying from a grey and also they still might string you along)
Secondly adding your name to a list for such a hot / in demand watch means little in this day and age and you will most likely never get the call as the list is probably imaginary and a polite way to say sod off.
It sucks but its the way it is right now unless you get lottery style luck.
In a nutshell you are 3-4 years too late. Things are crazy the past few years regarding hot Rolex Sport models.
If hellbent on getting a Rolex best chance is aim for a Black Sub / Explorer / Explorer II.
Try and get really friendly with a small local AD if you can and show your sincere. What you have to remember is that everybody now is seen as a likely flipper if your not a longstanding customer as essentially you can walk out the door with the watch and pocket a extra 4 grand 5 mins later.
