Calatrava

Appearing in the 1960s, the reference 3445 belongs to the moment Patek Philippe began building the Calatrava for daily wear rather than for the drawing room. Its gold case is sharply defined, with straight angular lugs and a stepped bezel framing a cleanly restrained dial. The movement is an automatic, wound by a gold rotor, which made this one of the house's most practical dress watches of the period. Collectors value it as the point where the Calatrava turned from a formal object into one you could wear every day.
