Basically the Rolex 666 offers a lot namely I don't worry about scratches on the crystal or case for that matter. But having said that I have added another vintage choices that are getting a lot of wrist time and no worries about scratches. The The Fat Lady 16760 with a twist. But to be honest scratching the plexi on any 5513 or 5512 in the collection does not bother me as it is easy to fix. The hesitation is only one of waterproof really swimming which is the only cause for hesitation in any selection.
