I own a Rolex DD that is over 25 years. I took it to Rolex Service Center in my country last year and they refuse to service my watch, unless I purchase a new Diamond dial. The cost of the Dial alone was $3700
Needless to say, I took it to a local watchmaker that was qualify and they did a spectular job on my DD.
This is what the watch look like before service.
These are photos after the service.
Just make sure you find a top watchmaker to service your watch
