the case did not crack. I am very familiar with changing straps on the pin cushion Radiomir, and indeed to Patrick’s point you often get either scratched case or screw heads.
I have seen a handful of collectors pair the OEM rubber with pin cushion Radiomir… and I would have never guessed it would fit mechanically due to the metal tube inside of the strap, since the natural curvature of the lug pins are curved.
I just noticed that your rubber strap does not have a tube. Ok it’s funny I never thought to remove that tube.
