Patek Philippe Calatrava
The Calatrava is Patek Philippe's dress reference — born 1932 from the Bauhaus principles of clarity, proportion, and restraint. Every modern Patek dress watch traces back to the Calatrava silhouette: round case, slim profile, minimal dial. The 5227R, 5212A "Weekly Calendar," 5226G, 6119G, and 6007G are the active references.
