Horological Meandering

I'm having an ongoing discussion about the authenticity of my IWC with some of my friends. I made an attempt to take them to the AD, but to no avail. They're so persistent that they just don't seem to believe! I am going to show your opinions to them. Har...  

I have absolutely no doubt as to the authenticity of both your Spitfire Chrono and the Big Pilot Antoine de Saint Exupery. I have no idea why they would question you... possibly just to aggravate you. A great pair of watches. Dean

find a reputable watch maker and have him open the case, if the movement is real then that is all you need to know as far as I am concerned.
