My neighbor recently got me a watch as an early graduation present. This is an AMAZING, very expensive, Invicta watch. It is made for diving so it can take a beating. The only thing I'm worried about is all the gross stuff that would get in the bracelet and watch itself. Do any of you have any tips for cleaning it or keeping it clean? (It is 18K gold) The only reason I ask is because he bought it for me to use in my profession so, if I can keep it clean, I really want to wear it! Thanks you all!
