The watch is not broken. Why would you think they would just give you a new one? The issues are merely cosmetic. The scratch is under the bracelet, not visible unless the bracelet is removed. I'm pretty sure everyone's Omega has some wear marks on the case. A good polish will remove virtually all of it and will not effect the value if you try to sell later. Nobody inspects a used mid-range watch that closely. You are probably going to end up with a like-new watch. Be happy. Like someone else said...this is a mass-produced watch, not a custom hand-built piece. There will be defects and imperfections, especially if you look closely enough.
If you want to make a big deal out of it, maybe negotiate for a free service when the time comes. The case polish, link replacement, and hand replacement should be expected, but you also have to add in a customer inconvenience and dissatisfaction factor...that should be worth at least a free service.
