They also replace the hands, all the seals, the pushers if it is a chronograph, crystal if hesalite, and maybe the crown (not sure about that one). I heard that sometimes for quartz they change the whole movement to update it to its latest revision, but it is better to let expert confirm that.
The service comes with a 2-year warranty.
The refinish is well done, no issue with the different surfaces. Deep scratches are left to avoid any overpolish of the watch. Bracelet is polished too. It won't become overpolished with only one full service by Omega. Just do not service it every year during 50 years..
Also, be aware that if last service was done by Omega, you can ask for a partial service. In that case they'll take the watch, inspect it and give you a price.
