You are absolutely right. I too have both the best versions of the Nautilus and Aquanaut, which are both sports watches. But I still cannot understand there is no demand for the ultimate dress watch, that is a basic Patek calatrava. There are a couple of basic/classic, good quality ones, with saphire crystals and Swiss ETA movements, but there is always some very obvious, glaring flaw. It seems that they do not want to go the extra step to make it perfect. For example the Swiss ETA with the silver movement and correct style gold rotor they put in the ultimate Nautilus is "very close to correct look" for any dispaly back simple/classic Patek. They use the same Swiss ETA movement is some of the high end simple/calssic Pateks, but with a wrong style silver rotor. Another example is that they will have the correct case, but wrong dial, or correct dial with wrong case etc. So it does not make sense
