Introducing Patek Philippe Aquanaut (ref. 5650G-001), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in white gold and measuring 40.8 mm in diameter, with a thickness of 11 mm, defined by a cushion silhouette. The caseback is open, and the crystal is sapphire, delivering water resistance to 12000 meters. At a glance, the dial balances texture and clarity: a blue tone, framed by arabic numerals hour markers, and stick hands. At its heart beats a proven engine: the 324 S C FUS AR caliber. Issued as a limited edition, appealing to focused collectors. Introduced in 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.
