New Rolex buyer looking for advice

[Mahavir]

Hi guys,

So, after a lot of research and thinking I've decided I want to buy a new Rolex instead of vintage. I live in the Geneva area (Switzerland) and looking to establish a relationship with some ADs here (I only know of Bucherer in Geneva but Lausanne also has l'Emeraude). Do you guys have any advice in terms of how to start a good, long-term relationship with an AD? I'd like to stick to one shop to make the relationship easier in the long-term. (I'm relatively new to the luxury watch market).

I'm currently interested in buying a black Submariner Date and a GMT Master II in the next couple of years.

Many thanks!
