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. 

The Ref. 4948 Annual Calendar for ladies in white gold has been endowed with a white Balinese mother-of-pearl dial. This adds a touch of very feminine finesse to the patented full calendar.
