Patek introduced the annual calendar in 1996 and has treated it since as the practical middle ground between a simple date and a perpetual. The 4947 arrived in 2015 as a smaller and more decorative reading of it, and the steel version on an integrated bracelet, shown in 2021, moved the reference out of that bracket entirely.

This Patek Philippe Annual Calendar Moon Phases wears a 38mm steel case with a blue shantung dial, day and month in twin apertures. Calibre 26-330 S QA LU inside, on an integrated steel bracelet.

Fun fact: Patek's annual calendar patent was drawn tightly enough that no competitor shipped a comparable module for roughly fourteen years. The complication is widely reported to have begun as a university engineering project.

The collection

Annual Calendar

The calendar Patek patented in 1996, set once a year at the end of February

Patek Philippe patented the annual calendar in 1996 and introduced it in the reference 5035, a self-winding watch that reads the long and short months by itself and needs one correction a year, at the end of February. It sits between a simple date and a perpetual calendar, since it knows which months run to 30 and 31 days but not February. The tell is three apertures for day, date and month set along the arc of a circle below 12, with a moon phase and 24 hour indication at 6 on many references. Patek files the family under Complications, and it runs from plain round gold references through the regulator, travel time and flyback chronograph versions to diamond set ladies models.

Sizes in the family

38 to 42 mm on current references, earlier pieces smaller

Who it suits

For the buyer who wants a calendar on the dial but is content to set it once a year, at the end of February.
