Does it work?

Here is a demonstration: https://youtu.be/jb7fI4dfRk4 

But does it work on mineral crystal as claimed? Any experiences? I know regular Polywatch is a respected product.

I just put a scratch in the beautiful but protruding crystal of my Tuna MM...

I've used it and while it won't work miracles, in some situations it will work. However, nothing beats replacing a crystal, if it is a financially viable option.

I probably will track down a crystal in time, but these aren't massproduced like more common model, so I guess it will be a challenge?

I don't mind a few sctraches, but there will be more due to the form of the crystal.

I also wonder if it will be harder or easier to apply this treatment on a domed crystal 🤔
