In regards to metal...
You have what appears to be an aluminum insert in very close contact to bronze metal.
All it takes is one scratch on the insert to allow for the spot corrosion seen.
Bronzes are more cathodic where aluminum is more anodic. The more anodic metal will break down before the more cathodic metal...
This would happen on a SST watch also...I have seen pics of the red BB with corroded aluminum bits.
Using dissembler metals on such an expensive watch seems like there is a break down in QC because a company like Rolex knows that the integrity of the anodizing needs to be 100% intact on the aluminum parts in order to mitigate corrosion. But to be fair it only take one tiny little scratch to really screw things up...they need to get rid of aluminum from their assemblies...
