Accompanied by Patek Philippe Extract from the Archives confirming production of the present watch in 1963 and its subsequent sale on 30 November 1964. Furthermore delivered with Patek Philippe original black and white archival image of reference 3504 model and Patek Philippe original fitted presentation box.
The present watch has never been offered at auction before and is furthermore the first example of any reference 3504 to appear in public to date.
Interestingly, reference 3504 was literally unknown to exist until this day and was not featured in any of Patek Philippe's brochures or literature. Its case design is comparable to the also water-resistant reference 3445; the dial however is distinguished by the large baton numerals combined with the typical Patek Philippe "dauphine" hands.
