Hello all. Im new to this forum. I inherited a Tag Heuer Aquaracer watch. Quite a lot of scratches. Gave it a clean and light polish. We notice some copper colour showing thru on the bracelet and on the case, where there has been wear and rubbing. What is this ? Are the not solid stainless steel ? Fixable ? Suggestion. (Yes, I know crown missing, on order) Thanksall.
