A contemporary Calatrava in 18K white gold, the 5226G-001 brings a more casual, modern edge to Patek Philippe's dress-watch line without leaving behind its essential restraint. The 40mm case and charcoal gray textured dial give this watch a quieter, more architectural presence than a traditional formal Calatrava. An automatic movement with date keeps the specification practical and current. At 8.5mm thick, it sits with the slim, composed profile collectors expect.
