I used to have a real beef about the flimsiness of the Oyster clasp, thinking that it had no place on such a costly, prestige watch (from the gen perspective, of course) until it was pointed out to me, that the Sub was never originally designed as a prestige piece, but intended as a functional tool watch: A stripped down for weight racing car, rather than a luxury sedan. Once I got my head round that, I found myself, not exactly appreciating the clasp more, as there are examples of better engineered clasps (Omega, UN etc) but it certainly doesn't bother me like it used to, so hopefully that might be of help to you in that regard With regards the rattling... I've found that oiling the bracelet improves the tactile quality of the bracelet, but not done a lot for any rattling... At the end of the day, the links move about and hit on each other, so they're going to make noise, just like pocket change does. I think the trick is to wear the bracelet at just the right tension so they don't rattle so much when on the wrist
