comparing Lange to Rolex is comparing apples with pies. Rolex makes great watches and I like the brand very much but Lange is in one league with PP and AP and definitely above Rolex.
Concerning your doubts of buying the 37mm version, I fully recommend, as mentioned above, to try out the 35mm.
Dealing with the quality of Lange (the guy who complained about that in your above quoted article): this is ridiculous!!! There is no brand in the watch industry that provides such a high quality standard as does Lange.
Keep my fingers crossed that you will find your perfect match!
