In April, Patek Philippe introduced a totally new perpetual calendar with an innovative patented one-line display
The manufacture has expanded its rich range of calendar watches with the addition of a perpetual calendar that displays the day, the date, and the month on a single line in an elongated aperture beneath 12 o’clock. To combine this unique feature with crisp legibility and high reliability, the designers developed a new self-winding movement Calibre 31-260 PS QL for which three patent applications have been filed.
The seemingly simple new face of the perpetual calendar display demanded totally new technical challenges. To assure the largest possible calendar display on a single line with optimized legibility, the developers were asked to design a system with two date disks – one for the tens and one for the units. So the calendar display consists of four disks, one for the day, two for the date, and one for the month – all four perfectly embedded in the same plane assuring optimized legibility, minimal energy consumption, and superb reliability
