Meet Patek Philippe Calatrava (ref. 3802/200J-001), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in yellow gold and measuring 33 mm in diameter, defined by a round silhouette. The caseback is closed, and the crystal is sapphire, delivering water resistance to 2500 meters. At a glance, the dial balances texture and clarity: a white tone, framed by roman numerals hour markers, and stick hands. At its heart beats a proven engine: the 315 SC caliber. 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.
