Shy wearing my rolex..

[HappyAngel]

I have a beautiful midsize meteorite rolex and I don't like to wear it in front of people (like co-workers) When I do wear my rolex to work, I always wear long sleeves to cover it up & also....to protect it from being scratch. I don't want my co-worker to know that I own a rolex.....how should I respond if my co-workers ask me about my rolex? People at my workplace don't wear nice things. I feel awkward if they see my rolex & I don't want people to talk behind my back....do you guys have any suggestion as to what I should say when they ask about my rolex? Should I just say "it's fake"? But I think my watch doesn't look fake though. What if they ask me to let them see it close up? How should I answer them without being rude?
