Manufactured from 2004 to 2011, reference 5970 was Patek Philippe's very last perpetual calendar chronograph wristwatch series to use a Lemania 2310 based movement. With the introduction of successor reference 5270, Patek Philippe used its own in-house movement. Platinum reference 5970P examples, like the present watch, were only produced from 2008 until approximately early 2011, with, according to scholarship, only approximately 300 to 500 examples estimated to have been made.

Due to its generous and modern case proportions, this reference is a favorite among scholars and the watch community. Since the model was discontinued, it has only increased in popularity and collectability. Compared to its predecessor, the reference 3970, reference 5970 has a significantly larger and heftier case size of 40 millimeters.

While the reference has enjoyed variations such as different gem-set bezels and various dial designs, examples cased in platinum like this watch are true classics. The black dial immediately distinguishes the case metal as platinum, as does the subtle diamond between the lugs at 6 o'clock. Fresh-to-the-market and beautifully preserved, the present lot is offered in excellent, hardly ever worn condition and is accompanied with its original Patek Philippe Certificate, product literature, leather envelope, and presentation box.
