·A replaced crystal is no problem, especially since it will be replaced with a genuine crystal at an official Omega watchmaker.
I think, on the outside they will just slightly polish the stainless steel case and perhaps work a bit on the hands/dial. They will probably re-lume the hands and perhaps the hour markers although I can't see whether there's something wrong with them due to the quality of the picture apart from the fact that, probably, due to age they no longer light up.
Crystals can be polished but it reduces their durability and also their water resistance. It also depends on the type of damage they have (scratches/cracks).
