Rolex CPO and voiding warranty

[Rickynelson]

Hi all,
While looking at buying another Rolex from a grey dealer,
An official Rolex CPO salesman (if I can call him that ) raised the following with me, and I quote:
“
Beware that Rolex service centers will no longer polish or service watches that come from grey dealers, so for example a 2023 watch in "unworn" condition could have been scratched and then polished by an unauthorized watchmaker before sale, and Rolex can detect this unauthorized work and would decline any future work, or charge an extra fee to restore it to their standards.

Since the launch of CPO any unauthorized work on a watch would void this 5 year warranty. It depends if you get lucky that this hasn't been done to it. “

Using the wisdom of this fine group, what is your take on this
I thought this might be relevant to others.

Cheers.
