Polishing or not.

I inadvertently lightly scratched watch, the watch can be polished without damaging the edges?

Welcome here on this great Forum! It's hard for us to diagnose this, you best take the watch to a IWC jeweler for an expert opinion. In general, IWC does a magnificent job and can make a watch look brand new.

From your other post I believe that you bought yourself a 3717 again after selling your first one? The 3717 is a great watch so enjoy and wear it in good health!

Kind regards,
