Have a question for royal oak owners.
I purchased a jumbo a few months ago and have been very happy with it. However, there are some black on the stainless steel bracelet. They are where the clasp meets the bracelet and it seems there are some black marks on the clasp as well. Is this normal, and how would you go about cleaning it off? I have tried both hand soap, dish soap and a soft toothbrush to no avail.
