A new face for a brand-defining grand complication

An innovative display mechanism crowned by three patents

To assure the largest possible calendar display on a single line with optimized legibility, minimal energy consumption and superb reliability, Patek Philippe engineers developed a calendar display consisting of four rotating disks – one for the day, two for the date and one for the month – all four perfectly embedded in the same plane. This patented mechanism alone required 118 additional parts in comparison with a conventional perpetual calendar display.

In the following video, discover the inner workings of the new self-winding mechanical Caliber 31-260 PS QL.

Perpetual calendars, a classic grand complications par excellence

Perpetual calendars have always been prominently featured in Patek Philippe’s collections, offering a wide range of design elements with analog or aperture displays and dial configurations.
