About the Model

The Patek Philippe Perpetual Calendar Chronograph Platinum Diamond Black Dial 40mm Ref. 5971P-001 is a statement in high complications, crafted from platinum and set with 42 baguette-cut diamonds on the bezel. This reference, introduced in 2010, features a 40mm case paired with a black dial and applied diamond hour markers, combining practical horology with gem-set artistry. The hand-wound Calibre CH 27-70 Q movement delivers a 60-hour power reserve and powers the perpetual calendar and chronograph, including indications for day, date, month, leap year and a day night display, all adjusted through column wheel chronograph engineering. The watch is presented on a white alligator leather strap with a platinum pin buckle for added refinement. Protected by a sapphire crystal and water resistant to 20 meters, the 5971P-001 remains a landmark in Patek Philippe’s catalogue, merging intricate calendar and chronograph functions with a luxury presentation rarely seen in complicated timepieces.Read More
