Got asked by a couple of work colleagues (both older and more senior) what type of watch I was wearing, while rocking the white face/blue hand Parnis (with original black strap). I said it is not a very well known brand but that I really like it. One of them asked "how much did it cost? It looks like a $2000 watch." Caught me off guard, didn't want to lie and inflate the value and i'm not the kind of guy to forget the approx amount something cost, so I said $70. They were both shocked.
Wish I had said it was a gift or something.
You should have said "Sir, It's a blatant rip-off of an iconic IWC design."
