The patented annual calendar was launched in 1996 and has been a success story for the past 20 years. Indicating the day of the week, the date and the month, and requiring correction only once a year, this ingenious mechanism has emerged as one of Patek Philippe’s flagship models. It offers a choice of different displays and nuances of style, always combining elegant lines, noble materials and lavish attention to finish.
