路The only watch I have with hollow end-links is an old Seiko that rattles like crazy. Actually, all the links are stamped/bent not solid. Anyway, maybe that's why I'm thinking it would cause a lot of case scratching.
It all depends on how well they were manufactured and then how well they were fitted to the watch. Your watchmaker can fit the end links if you're at all concerned about it.
