I've got a Breitling Datora that has badly worn gold plating on the case. I'd like to swap the case with a spare that I have from another Datora. The replacement case is without the corresponding buttons in the side of the case to set the Month, Day, etc. Is it a major deal to swap these buttons from one case to the other? Not planning on doing the work myself but will use a watchmaker I trust. Thanks.
