Given the large amount 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 was available only in platinum with a grey 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 calibre 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 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 indicator. Officially out of production from 2014, the watch is sold with its Certificate of Origin confirming its subsequent sale the 12th November 2007. Accompanied by a Patek Philippe Certificate of Origin confirming the calibre, movement, reference, case material and the sale in 2007. € 38000 - 70000
