Probably not. It sounds like you may have some concern over the Survivor and it may be a decison between the RBII and the GP. There has to be one that really sings to you above the others when yo put it on your wrist. Sometimes we can over-think these things and it is better to just let your wrist decide. I thin it is a mistake to dwell on which watch has which movement, whether this case will scratch more easily than that one. You are comparing three of the most audacious and interesting ROOs, so you really have to just go with the one that gets your heart racing the fastest.
For me, it is the Survivor. I hope you decide on one of the others so that there is one more Survivor out there for me to hunt. ;-) (I should probably be expelled from the PuristS for that comment, right Ming?)
The GP is surprsingly one of those watches that looks better in photos than in person -- to me only, as I do not think that is perhaps anyone else's experience at all. But it may have also been the case that I was trying on a Survivor at the same time, and when I put on that beast, there was literally nothing else in the room. Of the three you are considering, the RBII wears the biggest, again IMHO, as it is a beefy watch. As at least one other person commented here, however, it may be the most beautiful ROO ever...I am not sure I could disagree with that
So, getting all three is not an option, right? ;-)
Good luck,
