Reference 5970 is the proud heir to Patek Philippe’s legacy of perpetual calendar chronographs starting with the reference 1518, followed by the 2499 and 3970. Launched in 2004 and in production for only 7 short years (making it the shortest run for any perpetual calendar chronograph model by Patek Philippe), reference 5970 was discontinued in 2010 and replaced by reference 5270 that houses Patek Philippe’s first in-house chronograph caliber. Reference 5970 relied on a heavily modified Lemania base movement. Whereas the reference 2499 (2nd series onward) and reference 3970 featured round pushers, reference 5970 comes with rectangular pushers giving it an incomparable resemblance to the highly coveted and über rare reference 2499 1st series. Upon launch, this model became an instant success and since its discontinuation, it has only increased in popularity and collectability. While the reference has enjoyed variations such as different gem-set bezels and various dial designs, examples cased in yellow gold like the present watch are believed to be the rarest metal. The present watch is furthermore offered as a full set with its Patek Philippe Certificate of Origin dated August 22, 2009, additional case back, hang tag, setting pin, presentation box and outer packaging.
