It is a classic round wristwatch that symbolizes Patek Philippe, announced in 1932. A pure form and a refined Dietel, it has been favored by a wide range of generations over time. The name "Calatrava" comes from the Calatrava cross, the emblem of Patek Philippe, and is the mark of a brave Spanish knight. Its unobtrusive design is inspired by the German architectural and decorative arts movement Bauhaus, whose function determines its form. It is a deep-rooted popular collection whose materials and movement have evolved year by year.
