Using this Youtube video method to fix a scratch on the apple watch glass...consequences?

[Honey Badger]

Came across the youtube video below to repair a scratch on a watch crystal...would this procedure work on an apple watch? I would think it would destroy the touchscreen capabilities of the apple watch or have some negative consequence. Any thoughts?

Might work on the sport but I can not see the average person doing this with great results.

You will wear/damage the coating on the glass, although I doubt it would ruin the touchscreen features.

I will rather deal with the minor scratch on it, and use the apple care to replace it later when it get worse.
