Omega 1020 movement

[Xppx3]

Hey guys,

I was looking at the movement of my 1982 seamaster earlier, and was curious about a circle-hole-thing that seemed to serve no purpose. So, I googled some pictures of the movement and found that my serial number, 45378505, seems to be in the wrong place. Instead of being the this circle-hole-thing, along with the Omega logo like in movements on the interweb, it is above this circle-hole-thing. Should I be concerned?

This is where it should be (pic from internet): http://1.bp.blogspot.com/_a5BOKXYYUA...ega+1020M1.JPG

I apologies for the bad quality, but you hopefully get the idea.
