Cracked or scratched face, how to tell?

CDarby

Not really sure if this thread belongs here as my query is specifically related to a smart watch, but anyway, here goes.

Does anyone know how to tell if a watch face has been cracked or if it's merely scraped?
My watch has a lovely line going from 6 o'clock up to say 10 o'clock, fairly straight, I cannot feel it as a crack using my fingernails, and so think it might only be scratched (fingers crossed)
Does anyone here have any sure way to find out for definite, and If it's just a scratch, anyone any tips to remove it?

If it is a light scratch then can be easily removed.
There are solutions out there that you can buy but the old toothpaste method can be a good one. Google it.
I use a solution called polywatch which is great stuff.
Always check that whatever solution you use will work with your crystal type.

If it's an acrylic IE plastic crystal then things like polywatch will work, but all the smart watches I've seen had some sort of glass material and polywatch won't work. There are other pastes that can polish glass, but they're nasty to work with and take ages to polish even very light scratches. Generally you have to polish by hand too as using a buffer like say a Dremel will usually result in putting too much heat into the glass which can cause a crack.

If it's a smart watch there might be a protective screen type glass you can put over the glass to protect it, this can also hide scratches

I've never used them for a watch but have used them on phones with cracks in the past and they're great.
