Watch face and guarantee card don't match,

[Crosswit]

Hi all,
I live in the UK and was all set to buy a new Rolex Datejust 36mm with bi-colour jubilee bracelet with champagne, baton dial. I went to a reputable jewellers who holds the franchise for Rolex in a large shopping centre and they ordered it in. I have just been to the jewellers to buy the watch but before parting with my hard earned cash I thought I'd check the watch against the guarantee card. Although the serial number and model number matched there was a discrepancy in that the watch itself has a champagne dial with batons but the guarantee card said "WHITE ROMAN NUMERALS". I even photographed it as proof. The salesman said that they had been having a problem with the new cards and if I bought the watch he'd sort it out and get a new card for me! I politely refused saying I wasn't happy to buy the watch and take it when the card does not match up. He is going to look into it and contact me tomorrow. I don't know what's going on as I thought there would only be one of these cards for a specific watch and it would be impossible to obtain another card from Rolex. Please could someone give me some advice? Should I accept the watch if he manages to come up with a new card or does this sound dodgy and should I go elsewhere? Thanks in anticipation for any replies.
