The Reference 1436 was the first split-seconds chronograph wristwatch to be produced with a dedicated model number and was manufactured between 1938 and 1971. The first Patek Philippe split-seconds wristwatch chronographs were up to 50% more expensive than the simple chronograph [Huber, M., Banbery, A., Patek Philippe Wristwatches, Vol. 2 Second Edition, p.81]. According to our research, approximately 140 pieces were made, equating to an average of just 4 watches a year. 

Please note that the dial was exchanged with another one from the Ref.1436 made around 1960 however confirmed by an extract from the archives from march 2015.
