Given the large number of watches produced in the history of Patek, succeeding in creating an object that could be the first with a certain set of characteristics becomes increasingly difficult for the Swiss Polish brand but in 2006 was introduced the reference 5960. It is the first self-winding chronograph wristwatch to be fitted with an annual calendar complication. In fact, it was Patek Philippe’s first automatic chronograph ever produced. At the beginning it was available only in platinum with a gray dial and in 2009, this version also appeared with a steel/blue dial and became available in pink or white-gold while in 2014 was released in stainless steel. It is equipped with the in-house caliber CH 28–520 IRM QA 24H. Anyway, the original version, such as the present watch, remains popular as it marks a historic moment in Patek Philippe’s history. This lot is offered in very nice and almost unworn conditions, with a perfectly preserved case and sharply rounded pushers. The dial is untouched and perfectly combines day, date and month apertures, a power reserve display and a subsidiary dial for the chronograph with day and night indicators. Officially out of production from 2014, the watch is sold with its Certificate of Origin confirming its subsequent sale on the 8th of August 2008. Estimate € 50000 - 100000
