I would like to thank you for this post, and would also like to add..
I have purchased the IWC pilot's watch chronograph Top Gun 3 months back, and noticed after reviewing fake ones that a major distinction between them that is unmissable is the minutes and chronograph seconds hands.
Those two hands have a slight angle at the end of the tips.
I suppose to make it more accurate when reading the time on the original.
