"These watches are real art pieces from an era when you didn't see the crowd of divers that flood the market today, at prices that are absolutely out of this world."
True.
I have a few 1960s/1970s dive watches that I held on to over the years...Bulova Devil Divers (auto and Accutron), Caravelle manual wind and auto, Aquadive, Zodiac Sea Wolf, Benrus Citation, Hamilton two crown compressor, Citizen 62-6198, Wittnauer etc and imho they out class what is available today. Out class, not out perform of course.
