Wear them, bump them, scratch them, knock them. They are but things.
If wearing an Ebel makes you smile, don't deny yourself the pleasure because it might get scuffed up.
Some guy on Timezone once posted a close-up photo of his $50,000 annual calendar. It was completely scuffed up with bruises and scratches - but he loved it, and so did everyone else. A watch you love is meant to be an extension of you: your personal style, taste, and passion. At the end of the day, every mark is a piece of history - the history of your life. How exciting and memorable it is ten or twenty years down the line depends on you.
