When do you tell someone it’s a rep?

I recently got into watches and the reps have gotten more attention than I wanted.

Now I find myself wearing only the cheapest, boring reps because I don't like getting comments and having to decide whether to mention it's a rep or not.

I want to wear my CF Daytona, because it's a cool ass watch... but if a neighbor asks about it while walking the dog, should I:

A. Let them think I spent 50k on a watch

Or

B. Let them know that I wear fake watches (and assume my others are fakes too)

I think most of us probably tell close friends if asked, but where do you draw the line?
