Hi Nicolas,
The bracelet and quick release deployant make the Mark XV very comfortable to wear.
I didn't know any of the Rolex 6542 history so it was interesting to go searching. The nicest thing to me about white or cream dials is the way blue hands are highlighted. The white dialed Mark XV has a lovely blued second hand which is my favourite aspect of the watch.
Regards
Andrew
