Have hammerhead bronze, may be different from brass, my experience with no swimming, just normal usage: case oxidised fast, bezel oxidised comparatively slower, bezel notch (inner portion) still not oxidised till date
Yep, will do so.
Wanted to take pictures and ask yesterday, but forgot.
It's not super obvious, but the bezel is now a bit more rose/dark color. And of course, the crown has always been a brighter color.
