Box Contents
I recently picked up a Z blue Milgauss. I'm trying to determine if the box contents are correct and complete. The warranty card shows a purchase date of June 2016 so I'm assuming the production date was either late 2015 or early 2016 if the piece didn't sit on the shelf too long. Is anything missing and is this correct for this time frame?

Oman crest engraved on back
I am aware that some Rolex watches bearing the Oman crest on the dial are considered to be collector's items. When you Google search Rolex Oman crest or similar, you can find a lot of examples of those.However my question is in reference to a watch with no crest present on the dial, but with the crest engraved on the back. Does anybody know about these watches, are they rarer than those with the crest on the front? Or does the lack of crest on the dial suggest that the dial is not original (or the back is not original, same difference!)Any information would be greatly appreciated. The watch in question has a 6 million serial number.
