Patek Philippe gives fresh momentum to the emblematic Calatrava model featuring a guilloched hobnail pattern also known as Clous de Paris by treating it to a slightly larger diameter and a design reinterpreted in a contemporary spirit. The faceted applied rose gold hour-markers, combined with dauphine-style hours/minutes hands, create a sleek and timeless dial aesthetic. The elegantly refined rose gold case houses the new manually wound movement 30-255 PS with a 65-hour power reserve.
