I have two watches whose watch crystals scratch very easily. The scratches on them were both seemed unsightly and permanent. With just a dab of this stuff and two cotton balls, the scratches were removed from the first watch in less than 2 minutes. I thought it was a fluke. But after I applied it to the second watch and the scratches disappeared I was fully convinced. Folks...this stuff works on watches.

Just a sidenote: I later tried to remove the scratches from my cell phone. It did not work.
