The Annual Calendar is a Patek invention of 1996, a full calendar needing one correction a year, patented and never bettered. It made complicated watchmaking wearable every day.

38mm 18k rose gold houses this Annual Calendar (2020), running an annual calendar, topped by a mother of pearl face. The 324 movement drives it.

Fun fact: Patek patented the annual calendar in 1996: it tracks every month except February, so you set it once a year and leave it. It was the first genuinely new calendar complication in fifty years.

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.
