Can this be fixed?

Yes, my mistake, not under the glass and I’ve heard it does get scratched up which is fine with me as even my Rolex Hulk has its scratches. My issue is more how deep it looks and I’m buying used (obviously). When I get it serviced, I would like that completely removed.

Well, I guess that depends on how much is the asking price for this watch...

$7500

Everything I'm saying in this thread is based on estimates and personal opinion.
That being said, I think a full service from Omega in which they will polish the case can probably make this nick go away.
Assuming that's true, you're looking at approximately $500 (according to the Omega site), if they can't polish it and have to replace the case I believe the service cost will be much much more.
So let's say you can get this watch for a total of $8k (price of the watch plus the service), how much is a pristine once?
Take the difference into consideration but also factor in the "risk" that Omega can't polish it (you can always refuse the service and take it to a watchmaker that will be able to fix it instead of replacing the case).

Personally, if it was me I would have gotten a watch I can either live with it's flaws or get a flawless one.
Just having to go trough the process of getting it and then sending it to be fixed which can take months is just not worth it to me.
Time = Money

Thanks everyone. I'm going to keep looking for a better one.

Try and get something off the asking price, live with it for 2 years until you put it in for service, then when it comes back worry about bashing it into something else. Rinse and repeat for as long as you own it. Think yourself lucky it's not hesalite, we live on a knifes edge every day.
