Accompanied by Patek Philippe Extract from the Archives confirming production of the present watch in 1960 and its subsequent sale on 28 July 1961. The present watch has never been offered in public before.
Since its introduction to the market in 1938, reference 1436 remained the best known split seconds chronograph model produced by Patek Philippe. It was predominantly cased in either yellow or pink gold - no examples are known to date in white gold or platinum. The elegant reference 1436 and its high quality and complex movement certainly marked a peak in the evolution of technical wristwatches - an area in which Patek Philippe has been foremost for generations.
During over 30 years of production, reference 1436 saw a fascinating development both technically and aesthetically. Numerous dial designs have been given to this model. Until production of reference 1436 was discontinued in the early 1970s it has seen two different constructions in regard to how the chronograph seconds hand would be split. On the first generation of this model, made until the late 1940s, the crown would serve as a button to split and reunite the two seconds hand. The second generation, such as the present watch, was fitted with a co-axial push button within the crown for the split seconds function.
The present watch, previously never offered at auction, features an interesting variant of the silvered dial with tachometer scale. Typical for the last generation of this model, the dial now omits an additional railway track, "chemin de fer", for the fifths of a second. The overall look appears lighter and more modern. Such dials, usually fitted with baton numerals throughout and much rarer than the classical design used in the 1940s and 1950s, are testimony of Patek Philippe's attempt to modernize their chronograph models such as references 130, 1463 and 1436.
It is the first time a split seconds chronograph is offered publicly with a so-called "modern" dial without railway track, but still featuring Roman numerals at twelve and six o'clock.
