watch box information with pictures

[busstop]

I recently ran across a watch box that says Rolex on the inside. This box is a greenish blue color and approximately 8 inches long. I have no knowledge on Rolex watches or watch boxes and would like to know if there is a way to tell if this is real or a fake to me it looks nice and is a solid case looks vintage but then I do not know about them. I did find something similar called a Oyster Watch. What i read says the boxes are numbered this box does not have a number does that mean its a fake. Most of the boxes I see pictures of seem to be square this is a long box.Thank you for any help. I am sorry I reposted this but i think i figured out how to post pictures this time.
