I'm assuming this will clean right up...
...without 'polishing.' I'd prefer to see the gold color...
I’m not sure I am a big fan of such an oxidation of the case (I should see it in the metal) but…
…I am certainly a huge fan of the 3970 second series 😉
I am a fan of a nice gradual patina on the dial....this doesn't work for me at all.
....just being honest. .
I guess I don’t consider the case being tarnished patina.
I think you can get most of that out with hand polishing with a dry polish cloth. It won’t polish out the scratches, won’t cause any fading of the hallmarks etc. The aging of the dial with color change is the type of patina I wouldn’t want to mess with. ...
