AR coating - can it be replaced?

[johnfm]

Looking at a watch on TZ.

Seller says there are some marks on the AR coating.

Can it be replaced?

If so, where?

If not, I assume you remove it (by polishing it out?).

I have read threads about sinn owners polishing the external ar coating off. (the only thing about sinn that I don't like)

some people say its quite easy some say its a right PITA.

Prety sure its been talked about on TZ. I was considering doing it on the 656 because thge finger prints were getting on my tits.

In short yes, there are a few watch modders that can scrub the AR off and have it re done.

I have heard of people removing external AR with polywatch.

Not something I'd consider, myself, but the option seems to be there.
