Skydweller 326939 question?

[carl123]

Hi knowledgeable members.
Have seen a white gold Roman numeral skydweller for sale, it’s listed as new condition and pictures all look good and all in order. I have done lots of research on seller and have spoken on phone, companies house check and all above board.
My only query is how would it have a new style card with model and serial number on it when that model was discontinued in 2018 ?
I understand it has been sat in safe for some time, but surely when the watch was sent to the AD it came with the card, which was older style.
Thank you for taking the time to read and hope this makes sense!!
It’s a serious purchase and would appreciate your thoughts.
