My Grandmother had a good friend who was a very known watchmaker from the Netherlands. His name was Anton. He died a few jears ago and gave my grandmother a box of watches the he wanted do repair in future. She gave the box to me. Inside the were a few nice watches like my SEIKO 6139 6012, Roamer and a lot more. I will repair these watches in future and show the to you here on this platform. 😄
I have used it on my watcht ant it works out great. Of course it have to be a acrylic christal ( plastic ).
Tipp: First use your finger and rubb one minute clock and one counterclockwise. Then take a mikrofiber cloth and rub until everything is clear. You can repeat this process untill it is perfect, but don't do it to often otherwise there wil be no glass left 😂. Maybe it is good to cover the metall parts of the watch with some tape so you only polish the glass.
Here are some photos ( of the cover, before/after and the polish)
I could have done the whole process again but you can see the difference very well.
