Patek Philippe revisits the in-line perpetual calendar Reference 5236P with a vintage-inspired opaline rose-gilt dial enhanced by charcoal gray white gold hands and applied hour-markers.

Ultra-thin self-winding 31-260 PS QL caliber featuring a triple-patented additional module displays the day, date and month through a large single 12 o’clock aperture, complemented by two round apertures for the leap-year cycle and day/night indication and a moon-phase display.

The elegant entirely hand-polished platinum case is set with a diamond at 6 o'clock.
