What can scratch sapphire crystal?

I have been reading a lot about the hardness of sapphire crystal (9.0 on the Mohs Scale) and the fact that only diamond is harder. However, it seems clear that one can scratch sappire crystal. I know, because I have managed to get a vary faint scratch on the crystal of my U-series SS Sub Date (ahhhrrrgggg!!!).

It has been suggested that only three things you normally encounter can scratch a sapphire crystal:
- another sapphire
- a diamond
- silicon carbide, which is used to make such things as faux stone wall paneling and stone garden furniture.

Is this true?

I am not sure if this has been raised recently, but can anyone shed some light on the issue?? What do I need to sheild my lovely watch from???

Thanks!
