RSC Needs?

[a0asse01]

So I've just recently bought my Rolex (16610) and it had just returned from the RSC so it could be sold in as new condition as possible. So for the time being I'm good. But I know in due time I will need to send my watch off and I know its always been 5-7 years and now I'm hearing 10. Assuming you watch is being used just for normal wear and you don't see any issues with anything, is there a need to send it sooner than later? Is using the moto "If it ain't broke don't fix it" good, or should I have a "timer" so that I should send my watch out when the time comes?

My father has had his for 20 some odd years and to my knowledge he's never sent it back. Certainly not within the past 15 years. I've never seen that watch off his wrist for longer than a couple hours.

Thanks
Andrew
