Introduced in 2021, the 5236 is powered by the automatic Calibre 31-260 PS QL, developed specifically for the reference and featuring Patek Philippe's patented in-line perpetual calendar display, which presents the day, date and month together in a single aperture across the top of the dial for outstanding clarity and legibility.
