Question about warranty work

[Rolexmarc]

As I just purchased a new old stock watch from my AD. Naturaly it comes with rolex 2 year warranty. The watch via serial numbers is from 2006, and now discontinued. This makes it at least 8 yrs old. It seems to be keeping within COSC requirements. I am worried about the possible lack of lubrication left on critical parts, and the possibility of dried seals. Woul you wear it for 2 years and then send it to rolex if it starts going out of COSC standards, or should I send it in now? Appreciate your help.
