Anybody any idea what has happened to this gold 1675 gmt bezel?
It has small craters to the surface, like a sort of corrosion. But it is gold...weight exactly the same as another bezel I have (forgot, but something like 3.4 grammes or so), so not likely to be a steel bezel with a very, very thick layer of gold on it.
Could it be a fake bezel in real gold with craters from the melting and forming process?
Anybody seen this before?
