Annual Calendar Chronograph Ref. 5905P
Among the most coveted Patek Philippe complicated watches, two functions stand out. They are the annual calendar, which needs correcting just once a year, and the chronograph. So as to satisfy its public, the brand has again united these two complications, in the platinum Ref. 5905P. In 1996, Patek Philippe was awarded a patent for its annual calendar. Ten years later it unveiled its first self-winding chronograph movement, developed and manufactured entirely in-house. It was combined with an annual calendar, thus perpetuating Patek Philippe's heritage in calendar chronographs. A tradition that lives on in this new timepiece.
