I don't know why many worry about the finish on the Rolex movements, it's not like they are visible anyways. They are very reliable, robust and easy to service. Who really cares if it is decorated when their watches doesn't even have a showcase back?
With that said, I do wish Rolex opened up and showed off what they could do in the new Cellini line. I know they can make nice as they demonstrated in the Cellini Prince casebacks.
