Just like all those people with a framed Monet or Picasso print on their walls want their guests to think it's real?
I call "nearly, but not quite" as most of the time, I wear replicas to fool myself; to play a game of "if only this were real, cos it looks good". I know that in any given day, no-one will ever spot my watch for a replica because most people would assume it cost the same as a Timex, never having heard of Panerai or IWC.
Recently, some blokes I was working with had my IWC GST in their hands and were marvelling over it, as I'd said it was exotic, Titanium and Sapphire, and an automatic mechanical watch. They were impressed, more than I thought they would be, but didn't have a clue who IWC were. One of them said "Nice, but I want a Breitling" meaning he'd heard of non-rolex brands. For all I know, they assumed it was merely a very nice $500 watch, which it nearly is, costing in the gen dial and cost of Ziggification. I digress.
I like to think I have. It's a Rolex print or a reproduction Panerai to me. I'm fooling myself, not others.
