IWC Portugaise 2000

Hello,

I own a Portugaise 2000 (limited edition N°3XX/1000) and there is no number under the crown but inside the box you can read the number 2785257.
Is this normal?
Thanks for your answer.
best regards

What do you mean by "under the crown" ? The ...

number should be on the caseback.

That is not normal. The case number is on case.

Here is a photo of where the case number should be.

That is not normal. The case number is on case.

my watch seems to be 100% authentic. It 's weird.
do all the portugaise 2000 have a case number?

That is not normal. The case number is on case.

The number on the movement is 2785257 but there is no case back.
Everything is ok on this watch. How is it possible?

Could it be a replacement case?

I know this watch (rico76 is one of my friend) and it seems all authentic...
Nevertheless, no number engraved on the case...
