Introducing Ref. 4947 Annual Calendar For Ladies From Patek Philippe
Patek Philippe knows all about complicated timepieces and one of them is the Annual Calendar. Patent holder since 1996, the haute brand from Geneva presented the first annual calendar ever: Ref. 5035, after four years of research and prototypes. Able for the first time to distinguish between months of 30 and 31 days, needing to be reset only once a year at the end of February, it was named “Watch of the Year 1996”.
