A very fine and rare 18k yellow gold split-seconds chronograph wristwatch.
With Patek Philippe certificate of Origin and Extract from the Archives confirming production of this watch in 1959 and its subsequent sale on April 17th, 1961.
Shortly after the introduction of the "the simple" chronograph 130 model, Patek Philippe launched reference 1436 with the same case design, but featuring also split-seconds chronograph mechanism. Cased predominantly in yellow gold, examples in rose or pink gold are exceedingly rare. Only a very small number of watches have been cased in stainless steel and are today amongst the rarest, most sought after and valuable collector's watches.
