Pre-Owned Patek Philippe Annual Calendar Chronograph 5960/1A

Patek's ref. 5960 made history in 2006 as the manufacture's first in-house self-winding chronograph. The steel 5960/1A arrived in 2014 with a 40.5mm polished stainless steel case housing caliber CH 28-520 IRM QA 24H with flyback chronograph, annual calendar, and a 12-hour monocounter at 6 o'clock. Discontinued in 2018 after a four-year run, it left a genuinely short production window in both white and black dial variants. Every example available at The 1916 Company is fully authenticated and covered by our 2-year warranty.
