Patek Philippe 5270 & 5271 Perpetual Calendar Chronograph

The Patek Philippe reference 5070, part of the Complications collection, marked a significant return for the brand to large-format chronographs. Introduced in 1998, it was the first non-perpetual calendar chronograph produced by Patek Philippe since the reference 1463, which ceased production in the early 1960s. Its design drew inspiration from a unique Patek Philippe aviator's watch from the 1940s, characterized by its prominent case and dial layout, yet reinterpreted for a contemporary audience. This reference established a new aesthetic direction for the brand's chronographs, moving towards more substantial case dimensions.

The watch features a 42mm case, initially offered in 18k yellow gold, housing the manual-winding Caliber CH 27-70. This movement, based on a Nouvelle Lémania ébauche, was extensively finished and modified by Patek Philippe, meeting the brand's stringent quality standards. It provides a power reserve of approximately 55 hours. The dial, in this specific configuration, is black, protected by a sapphire crystal, and the watch is water-resistant to 30 meters. The fixed bezel frames the dial, and the watch is typically fitted with a leather strap.
