Patek introduced the 5236P in 2021 with a world first: day, date and month in a single line across the top of the dial, read like a written date. Making three discs sit level in one aperture took a new movement and several patents.

This in-line Perpetual Calendar wears a 41.3mm platinum case with a salmon dial, moon phase at six and the in-line calendar window at twelve. Calibre 31-260 PS QL inside, on a brown alligator strap.

Fun fact: the date runs on two separate discs, one for units and one for tens, which is how the calendar fits in a single line without a large date mechanism.

The collection

Perpetual Calendar

The calendar that needs no correction until 2100, in series production since 1941

Patek Philippe built the first perpetual calendar wristwatch in 1925, on a movement made in 1898 for a pendant watch, and brought the complication into series production in 1941 with the reference 1518 perpetual calendar chronograph. The mechanism carries the long and short months and the leap year cycle, and Patek states that it needs no correction until 2100. One layout recurs across the family, with day and month in apertures below 12 and the date read by a hand around a moon phase at 6, while other references set the calendar out in subdials read by hands, run it in a single line across the dial, or sweep the date on a retrograde hand. They sit under Grand Complications in the catalogue, in round gold and platinum cases.

Sizes in the family

39 to 41.3 mm on current references, earlier pieces smaller

Who it suits

For the buyer who wants the calendar to look after itself, and will keep the watch running so it never needs resetting.
