AR Coating on PO8500 - how durable is it?

[kymwatchlog]

Recently I saw a FS post that the seller had declared there are "scratches on the AR coating when viewed from an angle".

I wonder how durable/resilient is the AR outer coating on the PO?

I have a habit of rinsing my watches with mild soap and water after wearing. To dry it, I clean it with an old face towel.

Will this action be "harmful" to the AR coating?

Thanks!

That won't harm the ar coating. The good thing is that it can be easily removed and the crystal looks new, just a simple polish will do the trick.

thanks,

You mean a simple polish can permanently remove the outer AR coating (when it starts to show scratches).

my initial thought was that the AR coating is not a strong coat (like our anti fog coat inside swimming goggles) lol :)
