    Sorry I have never tried the Polywatch kit but have had success in the past with cerium oxide.

    I just use diamond abrasive compounds from China. Works well for smaller scratches.

    Paul: are you in need of just a round glass crystal? I have hundreds in sizes from tiny to pocket watch. Most of the common sizes like for a 16sz Hamilton are gone but I have a lot of smaller ones. If you give me a size in mm I may have what you need and my price is free.

    Very kind offer Dave. However it's a 60s watch. A Citizen super jet auto dater I've picked up, after being inspired by a couple that were posted on the PX. The watch has a very deep chamfered glass, it's really scratched up.

    The model of watch is as below.

    I have a vendor in Boston that can polish a glass crystal. If you want to PM me i could make arrangement for you. I had them polish a glass crystal on a bulova prototype and it came out great. Brian

    Hi Brian, thank you kindly for your offer. I'll first assess the watch when i've received. I may choose to test out the diamond compounds from china or the polywatch as they seem readily accessible, should i fail, i'll give you a holler if that's ok.

    Thanks again for the kind offer of assistance.

    The only other thing worth mentioning which you may already know is that it requires a lot of buffing to remove material. I’d get the coarsest grit you can, so 10 micron plus.

    I had big scratches in my bulova and when they were finished it looked brand new. Let me know. Brian

    DON'T use Chinese made compounds. The grit sizes are not uniform and you made very well end up with a nice bit of 80 grit in your 20k.

    Polywatch is great for acrylic/plexi but doesn't work on mineral glass.
