Yup, That's what holding back my purchase on watches (with inner and outer AR coating) in the first place.
As I can foresee the scratches mark on its coating - its give impression on 'sore' marking and thus spoilt the appearance of the whole watch. But now, after learning the 'tactic' of removing the unwanted coating (+ 2 hours manual polishing), I feel better at ease with the whole episode..
I feel comfortable getting those watches with 'only' the inner AR coating.
Thank you - Nick, for sharing. We never stop learning new things everyday.
