PP movement and serial number

[johnnyo63]

Where is the serial number located on a 5227 calatrava(picture if possible-black out number) Also: I found the movement number: 3011xxx and under is 315/190. The serial number is 630xxx but I can't find it on the watch and only on the papers I received from the watch shop(very reputable dealer) Also: According to some numbers I found the movement number is to early for a watch that started production in 2013 but this could be wrong. Anyway- I have a letter of authenticity if its been faked in anyway and I can get a full refund.

I'm not expert but it seems the serial number is inside the case (not visible from outside). On older watches with solid casebacks, the number could also have been placed inside the caseback.
