Patek Philippe has launched a new self-winding perpetual calendar with a contemporary “vintage” style in a case with three-tier lugs as well as a lacquered cream dial graced with luminous numerals and hands. The timepiece was inspired by exhibits in the Patek Philippe Museum from the 1940s and 1950s. Its heart is a newly developed caliber 324 with double apertures for the day/month and an analog date.
