I wasn't aware that the watches were made for testing in extreme conditions, I was under the assumption that they were marketed as "approved for military use." Because of this approval gained, I was thinking that the company such as IWC and JLC were implying that the military departments actually used the watches they were named after. Obviously the Navy Top Gun pilots and Navy Seals don't use these watches so I was confused with the disconnect. After reading your post, I realized that I was the one making the assumption of this implication that I suspected JLC and IWC to be making and I have therefore altered my original thoughts and perception.
Thanks for clearing that up and in the future I won't assume that a company is implying that a military group uses their product just because it's a product that was tested with that military group. This is not an accurate assumption for me to make.
It's kind of assuming that Ferrari gives Panerai watches to its race car drivers, which is another example of a bad assumption.
