From research, I learnt that the rm case is made up of hundreds of layers of ultra thin carbon fiber prepeg tape as shown above. It is heated and compressed. It is finally carved.
The question is, does the pattern happen due to the heat or is it finished?
Anyway, it would be interesting if someone could add to this technical discussion. Perhaps one day one can buy the tape, heat it, and paste it to any watch and solve the pattern issue.
That being said, I like the curvature of the new model way more that the kvf models.
