Omega 165.002 case legit?

Hi everyone,
I just bought a nos case for my vintage Seamaster 165.002.
What I noticed is that on the new case the stamps are a little different.
My question is: is this a legit case? I am thinking that Omega sourced their cases from different factories and that could be the reason they are not looking the same. (I've read here also that this was the case this the buckles evolution and different stamping on them)
The case ordered from ebay:

The original case that came with the watch.


Size wise, the cases are the same.

Thank you very much

It's legit, it's sharp, but NOS is... optimistic.

Yeap, optimistic, true. I am glad that the lugs are sharp, this being the reason for buying it.

Thank you so much for the answers!! Really appreciated.
