I am not a Patek watch expert or Collector, but have inherited a 1959 vintage, 36 jewel, automatic, 18k gold,magnetic and temp compensated, double seal of Geneva Calatrava watch. Its in excellent shape, no major scratches, never been repaired. This watch was prized by my relative, and he always told me it was very valuable, but never told me a price. any estimates or old action results would be greatly appreciated.
