I have had my watch for about two months now and I can assure you it is my absolute favorite in my collection. However one thing I have noticed is how easy the ceramic case is scratched, strangely the scratches show up as white even though I would have thought that the ceramic was a uniform black color throughout. This is a real disappointment in what is otherwise a fabulous watch.
One trick I have learned, if you get scratches on your watch, get yourself a white rubber pencil eraser. I rubbed this over and over the scratch for maybe 15 min and managed to significantly reduce the white coloration of the scratch. It may actually be more of a mar then a scratch since it doesn't appear to have penetrated the surface of the ceramic material.
In any event, I thought I would make a post just in case others have the same problem, the eraser works great.
