The latest addition to the Calatrava collection, this new white gold Reference 5226 is a perfect illustration of Patek Philippe’s quest for excellence in all fields of the watchmaking art. Starting with the shape of the pure, round case for which Calatrava models have been renowned since 1932, Patek Philippe has revisited this by adorning the flanks with a Clous de Paris hobnail pattern typical of the Manufacture. So as to enable this guilloched motif to continue around the entire caseband, the designers have also devised a distinctive case construction in which the lugs are an integral part of the case back.
