Once again Genève 135.070 - help needed

Hi guys, here i am again in the need for your advice. In the wake of my recent entry in the world of Omega vintage, a dear friend of mine who isn't familiar with forum nor speaks english, ask for help.
He's in talk with a dutch seller who's selling a Genève 135.070 (just like mine).
These are the pictures he got; it seems good to me even if i'm not sure at all about the movement (near the "seventeen" writing there's something i'm not sure about).
Maybe case can need a slight polishing; on this topic i never understood if originally the case for this reference was meant to be polish or satin.
Price is fair enough to me; i'm talking about 500 euro and the seller states that "service history is unknown, but the watch runs well".

Will you help me one more time?

Thanks in advance.

anyone? i hate to seem unpolite, but he has a 24-hours window to arrange the deal and since he's been on hunting for a long time, i'd like to help him as much as i can.

Hello,for first omega is very good choice. This watch looks good and has great movement.its a bit overpolished imo. The price its not that bad but its not the deal of the year. For example i sold a very crisp one 2 months ago on chrono24 with 16mm original buckle for 400 euro.In overall its a great looking watch and there is good deals that could be found with a little bit of patient.here is a pic

To the OP, sorry but the photos make this very difficult to assess. I suspect the case is very heavily polished. The lugs should be squared and sharp like the one that Spruce has posted, which is a much better watch, for the price. This particular reference is not highly valued, so you often see them priced lower than Seamasters making them a good entry point into Omega.

What a beauty!!..Something like this on ebay sells almost at 400-500( with condition not even close to yours)

Thank you all for your messages, they're really appreciated. Just spoked to my friend and he will probably pass over.
@george kob I bought mine last mounth on chrono24, i don't know how i missed yours!
Have to say i know i paid a little more than the average of this watches, but it was my first one step into this world, and i felt comfortable with the guarantee offered by the seller at the time.
Plus, i wanted it crisp as yours and that was my shot.
