Born in 1932, the same year that the Sterns bought Patek Philippe, the Calatrava has served as an Patek Philippe's flagship dress watch. Designed with the principles of simplicity and elegance, the Calatrava has seen many variations over the years. While the size and the materials of the case have changed with the times and new innovations, these principles have always been foremost in its design.
In 1972, Patek Philippe launched the first Calatrava reference with the iconic Clous de Paris bezel. Clous de paris, or Paris hobnails, is a particular type of guillochage of intersecting hollow lines that form tiny pyramids. Usually found on dials, this guillochage on the bezel is what distinguishes this reference from other Calatrava models.
