Fake or not?

Hi everybody,

I am Zsolt from Switzerland.

I have found below posting on ebay tonight of a 6538:

Besides the fact that I am not sure whether the case has just a re-engraved serial between the lugs, as the seller claims or it is purely aftermarket, also the dial leaves me sceptical: I have never seen such a 4 line dial with the Officially Certified Chronometer in that font and also the color combination white gold white is strange to me for that period (1958).

What is your opinion? Can anybody help?

Looking forward to see your comments.

Cheers
