How many could tell that you're wearing a rep? Few of the people I meet have ever handled a Submariner in their whole life... I'm use to buy only rep of watches that I can afford or that people may think I can... (a 50,000 $ Patek? C'mon guys...) and I've owned many expensive gen in the past (Rolex 1601/14000, Eberahard Navymaster, two Breitling Chronomat, Universal Geneve Polerouter...)
And the nowadays rep are just stunning... Only a trained eye may catch any tiny fault/difference...
BTW... I would not say anything about my watches... I just let them guess...
