Catalogue Essay
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.

Due to its generous and modern case proportions, this reference is a favorite among the watch community. Since the model stopped production, it has only increased in popularity and collectability. Compared to its predecessor, reference 3970, reference 5970 has a much 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 the true classics. The black dial immediately distinguishes the case metal, as does the subtle diamond between 6 o'clock - both indicate Patek Philippe's use of platinum.

Fresh to the auction market, the present watch is offered with an additional case back, setting pin and its original certificate. Preserved in pristine condition, it must have been worn only once or twice throughout its lifespan.

Well-known for the Graves Supercomplication — a highly complicated pocket watch that was the world’s most complicated watch for 50 years — this family-owned brand has earned a reputation of excellence around the world. Patek's complicated vintage watches hold the highest number of world records for results achieved at auction compared with any other brand.

Patek is also well-known for their classically styled, time-only "Calatrava" dress watches, and the "Nautilus," an iconic luxury sports watch first introduced in 1976 as the reference 3700 that is still in production today.
