Rolex "10 year service intervals"

[W44NEG]

I've heard from a few sources now that Rolex suggest 10 year service intervals on all watches after July 2015. Firstly, can anyone state categorically that a genuine Rolex-linked person has confirmed this?

Secondly, surely it's totally dependant on the usage of the watch. In my Daytona review, I stated that if a watch was worn in the water every day, vs. a watch that desk dives every day, there must be at the very least, a need for the seals to be maintained?

Also, my 2016 Baselworld press release confirms the -2/+2 seconds certification, and also the 5 year guarantee, but it doesn't mention 10 year servicing at all.

I'd still follow the 3-5 year routine anyway personally but it's just bugging me whether it's dealer BS, or a genuine thing?
