Patek Philippe ref. 5970P
The Perpetual Calendar Chronograph is the quintessentially Patek complication in their lineup. With a Lemania based movement, this watch is a true collectors piece as the very first watch current president Thierry Stern released when given the keys to the kingdom by his father. This particular piece is even rarer with a french calendar - of which very few examples are known. The ref. 5970 marks a transition in Patek Philippe collecting from the Philippe Stern to Thierry Stern era - accompanied by its Certificate of Origin, box and extra caseback.
