7140R LADIES FIRST PERPETUAL CALENDAR

7140R – GRAND COMPLICATIONS
SELF-WINDING

  • In order to accommodate months with 31, 30 and 28 days, and february 29 in leap years, a movement must have a mechanical ?memory? of four years ? or 1,461 days.
  • This function requires a highly sophisticated mechanism, based on a complex system of levers and cams pivoting around their axes. This is a domain in which Patek Philippe has repeatedly leveraged its long-standing competence.
