In 2006, when Patek Philippe introduced Reference 5960, it was an instant success. As with most of their innovations, Patek crafted the first model in platinum; however, it did not take long for the company to add other metals and dial colors to the lineup. This Patek Philippe Ref. 5960R-012 is a one-year limited edition piece that combines a rose gold case with a black dial and white numerals on black background calendar apertures to stunning effect; it is a collector's item by any definition. This timepiece is in excellent condition and comes with its original presentation box and papers, as well as a 12-month limited warranty from Twain Time.
