Seems I read on one of the fora that there is an error in the V7 case, in that one of the reliefs for the case clamp screws is not correctly placed. I so, is this the problem? IOW...is this a V7 case? I always thought it was V6 but I know that Thomas said that he had been shipping V7 cases before the actual announcement.
There is actually a traditional case clamp under there as the screw will not back out far enough to clamp the movement. It will fall out.
