Lot Essay

With Patek Philippe Extract from the Archives confirming production of the present watch in 1936 and its subsequent sale on April 9th of 1938.

Reference 523, along with Reference 524, was produced from 1936 through 1940, and is one of the very few asymmetrical shape watches made by Patek Philippe. They were also used as driver's watches, because the shape allowed for better readability of the dial when on the wrist, holding the steering wheel.

References 523 and 524 were made with two calibers - the small round cal. 8"85 and more rare tonneau-shape cal. 9'''90. The main difference between the two references is the case back. Only a few hundred pieces of the two references were made overall.
