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. This new model is driven by self-winding Caliber 26-330 S C powering the hours, minutes, central seconds, aperture-type date and stop-seconds mechanism. This new reference is teamed with two interchangeable straps: one in beige calfskin with a nubuck finish and the other in black calfskin with an embossed fabric motif and beige topstitching.
