I'm not bashing FF (I don't have any reason to just yet), but if it's so damned good, then why isn't it an industry standard? If "proprietary" claims are to be made, well, I would have thought companies like Rolex would have spent the $$$ to come up with something similar, years ago. [I recall that Rolex has been using sapphire since the early- to mid-1970s -- one of the first companies.]
I've seen some reports of scratches on FF crystals and the "standard responses" that get dished out. I wouldn't expect it to be any different. Even if many more instances surface over time, I still don't think that it will change the overall consensus for some folks. I think it will end up as another "buy them or don't buy them" type of dynamic that has become all too common.
With all of that said, I believe that some of the watch collecting community may not wait for future instances to amass, and jump ship now. I think that many will have a "wait and see" attitude, and I think that there will always be those that will defend anything all at costs. :whatever:
