I just recently purchased a 1655 Explorer 2. I know from reading many posts that the best way to keep your watch clean is to use a mild soap, warm water, and soft bristle tooth brush. I am fully aware that these are tool watches that were made to withstand some of the harshest conditions. My specific question is concerning the bezel. I've noticed many Vintage Daytonas and Explorer 2s do not have all the ink still intact on their bezels. Fortunately mine is all there, however I am concerned that if I do clean the bezel it may vanish over time. Sorry if this sounds ridiculous. I feel like a kid who bought his first nice car and doesnt want to remove the paper floor mat coverings for fear that he may dirty his interior. LOL! Can any members give any advice or feedback based on their experiences?
