Based on those photos I say it's legit. Dial may have been re-done, but can't confirm.
What are the numbers inside the caseback?
PS: Should be 135.041. If "Seamaster" has been added to the dial, it can be checked by comparing the location of the two words to other confirmed examples.
It is a 135.041
Omega archive shows it under the 135.0041 with a generic black outline
I have found a few examples that Don’t have seamaster. None that Do.😵💫
my search was by no means exhaustive. Happy (prefer) to be wrong here.

I was going to say the only took that looks fishy is the fake buckle, which is an indicator of something amiss, but I now see that you added the buckle 😁
Having looked at the pics, I think your dial is an original Genève dial and that the Seamaster has been added later.
Whether done by Omega or another entity I don't know.
In the pic below you can see the horizontal box around Genève, the base aligns perfectly with the bottom of the text but the top shows that the word Seamaster is tilted.
The vertical box shows the Genève well centred, but Seamaster is offset to the left. The inking of Seamaster also seems to be heavier.
I wouldn't worry too much about it, it's still a nice dial.
I didn't check the other examples (some are 166.041 which seem to have many more examples of double names).
