AD wants to open watch that's under warranty

[MikeyV]

So, I finally broke down and took my slow DJ41 into the dealer where I bought it. The day before, I was at another dealer, and asked about checking the watch out on a timegrapher.

Backstory: DJ41 new in June 2018, ran perfect, fell to losing 6-10 seconds a day every day. Ran fine otherwise, power reserve very good.

The timegrapher showed an amplitude of 207 degrees, -9 sps. He de-maged it and it showed 227 degrees , -4 spd (in the FU position).
I timed it myself for two more days, and it was the same as always, -6 spd.

So I take it to my dealer, and they were talking about having their watchmaker OPEN IT! I reminded him that it was under warranty, and he said something to the effect that they were recently elevated to some status among dealers, where Rolex lets them do warranty work.

I've never heard of that, and told him so.

I left the dealer asking them to do a full reading on the timegrapher, and NOT open it. I asked them to call me after they'd checked it out.

Has anyone heard of this? I was under the assumption (and I told the guy at the AD) that all warranty work goes right to RSC.

He it could go to RSC, if that's what I want.

Thanks for any help!
