How do you tell if an Iwc watch is real?

Answer:
Take it to a nearby watchmaker or repairman for professional authentfication, especially if he is NAWCC accredited. A slightly less reliable test is to look at the movement, as people who make fake watches do not bother to put IWC markings on it. Comparing it to photos is unreliable, as the quality of the pictures isn't good enough for comparison.
