Aquanaut

Patek Philippe's Aquanaut is the Genevan house's rounded-octagonal sports watch — a steel case with the same soft edges as the Nautilus, paired with an embossed composite strap that reads more contemporary than either its steel bracelet or a rubber sport strap. The automatic Calibre 26-330 S C runs at 4 Hz with a 45-hour reserve, chronometer-adjusted in six positions and finished the way only Patek finishes movements. The dial's grid-embossed pattern is a Patek signature. It's a piece of haute horlogerie you can actually swim in, and the wristwatch that has quietly become the most sought-after modern steel Patek.

Genevan haute horlogerie, made to be inherited.
