It is this sort of analysis that makes vintage collecting so interesting IMO. While I do love new/newer models too, any person can walk into a retail store and buy what's in the case. It is far more interesting to look at collecting with something other than the perspective of a mere consumer. That is, a historical perspective, and why a particular piece may be 'important' to the collecting community, or just simply a piece one connects with a personal level (for example, a 'birth-year' watch). Thanks again for the write up!
