Hey gang, RESOLVED: it was my error. Some sort of residue, but cleaned off fine. ------- A horrible watch maker scrubbed the Crap out of my crystal and took with it a good part of the bezel. I'd really love to find an older style speedmaster bezel. I understand these are largely the same for many models. Ideally with hooked 7 style rather than the flat one. Here's a pic showing the original bezel and damage.
