Introduced in 1986 as the successor to the legendary reference 2499, the Patek Philippe reference 3970 represents an important chapter in the manufactures history of perpetual calendar chronographs. Produced until 2004, the reference combined two of Patek Philippes most celebrated complications in a beautifully proportioned 36mm case, powered by the manually wound calibre CH 27-70 Q.

The present example is particularly striking, pairing a platinum case with a glossy black dial. Applied white-gold indexes and matching hands contrast beautifully against the dark surface, while the twin chronograph registers, perpetual calendar indications and moonphase display create a remarkably balanced composition. The combination of platinum and black gives the watch a distinctly contemporary character while preserving the classical proportions of the reference.

Of particular note is the exceptional condition of the case. The distinctive stepped lugs retain excellent definition, with crisp edges and clearly preserved hallmarks. The sapphire display back reveals the beautifully finished movement, with its intricate arrangement of chronograph levers, bridges and wheels.

Manufactured in 2001, as confirmed by its accompanying Patek Philippe Extract from the Archives, this example dates to the final years of reference 3970 production. It is accompanied by a Patek Philippe service box and service hangtag. With its desirable black dial, platinum case and outstanding state of preservation, this is a particularly compelling example of one of Patek Philippes most important modern complicated wristwatches.
