Patek Philippe is adding a brand-new perpetual calendar with an original in-line display to its rich range of calendar watches. The day, date and month appear in a large single aperture at 12 o'clock. So as to combine originality, legibility and reliability, the watch design engineers have developed the new self-winding movement 31-260 PS QL with an additional in-line display module, for which three patent applications have been filed. This highly sophisticated new caliber is housed in an elegant platinum case framing a vertical satin-finished blue dial with a black-gradient rim.
