Hi! Question regarding official "extract from the archives"

[SAKHR47]

Hi,

My question may seem stupid to the experts that are hanging out around but I am trying to get the exact and correct information, so I try :)

On the PP "Extract from the archives" that you often see along Watch photos, I've came multiple time across this mention: "The above dial is not mentioned in our archives".

(PS : i can't post link, i apparently need more seniority here!)
I'm not exactly sure about the implications. Does it mean that the dial has been changed ? If yes, does it mean that the dial changement happened outside of the official PP service ? etc.

Thanks in advance for your precious informations :)

Best,
Ludovic
