As an owner of a RM watch, I always feel disgusted whenever I see a picture of a Cvstos watch. It's a pure knock-off - same case, styling, and crown. Simple as that, and I have nothing else to say on this subject.
As Gaz says above, if it smells like a RM, walks like a RM, it must be a RM knock off. Even the Romain Jerome Titanic DNA watches have more originality than Cvstos watches. That's just how I feel.
