Introducing Patek Philippe Calatrava (ref. 5522A-001), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in stainless steel and measuring 42 mm in diameter, defined by a round silhouette. The caseback is open, and the crystal is sapphire, delivering water resistance to 6000 meters. At a glance, the dial balances texture and clarity: a blue tone with matte finish, framed by arabic numerals hour markers, and sword hands. At its heart beats a proven engine: the 324 S caliber. Issued as a limited edition, appealing to focused collectors. Initial production year: 2017. With considered ergonomics, it feels composed during extended wear. Brushed and polished elements play with light to emphasize crisp geometry. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
