Hello - I ordered the cape cod cloth and since I was in Geneva, I decided to go back to Patek and they showed me pics when I dropped it off which show the patina at that point too. Strangely I cannot remember but the watch has been with Patek for 9 odd months, maybe I forgot. In any case they were kind enough to clean the case for me. Most of the patina seems to be gone now, I will try removing the remaining patina with the cape cod cloth when I get back home. Must say, Patek service is excellent, even for a customer like me who is not buying anything.
