About RSC Authentication

[llttt123]

Hey guys,

Not really a newbie here as I kept browsing this forum for 5 years already, but this is the first time I post. Long story short, I haven been waiting for my BLRO 4 years in HongKong now (yeah, with 20k PH) and still a no-go.
As I'm doing a business travel to NY next month, I decide that I'm gonna give the trusted seller here a shot. However, as an Asia based member, I have seen how scary those Franken and Rep Rolex can be (Thank you my dear neighbor Guangzhou...). I have totally faith on those sellers (DavidSW, Takuya) of not selling suspicious pieces, but no one can be risk-free besides AD and I just want a peace of mind (have the movement check even for an unworn one).
Here comes the question, IS RSC NEW YORK THE ULTIMATE ROUTE FOR AUTHENTICATION? From place where I'm from, The RSC has seized the authentication service for years. Is it the same here is NY or US? If RSC NY service my watch purchased(Service quote, Insurance Appraisal), should I still be worried about its authenticity?
