Reference 1436 is the first split seconds chronograph wristwatch that Patek Philippe ever produced in a series. Originally launched in 1938, the model was used as a "tool watch" to time horse or automobile racing, along with scientific experiments. The reference is possibly one of the finest watches ever produced by the firm, with the rattrapante chronograph mechanism housed within the confines of a 33 millimeter case. Predominantly produced in yellow gold, the model was very rarely cased in pink gold. In fact, research suggests that less than 9 examples are known to gave survived in pink gold, with exceedingly few examples featuring a pink dial, such as the present watch. Its rarity, and infrequent appearance on the market has caused the reference to cultivate a mythical status.

This watch combines, and displays, the rarest and most desirable components of the reference. An early first series example, this watch is nothing short of breathtaking and stunning. The pink gold case, confirmed by the Extract from the Archives and made by Emile Vichet, is preserved in amazing condition with sharp facets and finishes throughout. A hallmark is clearly punched to the left band, attesting to its crisp nature. The unsigned crown is correct and original. Early examples featured a crown that would act as a button to split and reunite the two seconds chronograph hands. It was only later that the crown was fitted with a co-axial push button the reunite the split seconds function.

Yet, the beauty of the watch lies in the extraordinary pink dial. The correct long signature is present, and all printing is intact and legible. The hands and numerals have aged with light patina, giving the watch so much character and history.

Rarer still, this example is complete with all its original accessories such as its original certificate, bill of sale confirming the watch was cased in pink gold, envelope and fitted presentation box. The bill of sale furthermore states that the watch was sold to Monsieur Victorio Luzuriaga, c/o Instruments de Physique for 1900 Swiss Francs in 1946. A scion of the Luzuriaga dynasty, Monsieur Victorio Luzuriaga was a member of an entrepreneurial industrial family. Making his fortune through land, machinery and technical factories, Luzuriaga was a great businessman whose wealth was diversified in the coal, naval and oil industries. One can only imagine the plethora of uses for a split-seconds chronograph wristwatch in Monsieur Luzuriaga's world of business and development.
