Aquanaut

Why it matters

The Patek Philippe Aquanaut is a sports watch with a tropical rubber strap and an embossed dial pattern, sitting under the Nautilus in Patek's lineup. It's the most accessible Patek sports model but still trades well above retail on the secondary market for the most-wanted references.

When evaluating an Aquanaut, the strap condition is a giveaway. Heavy creasing, cracking, or stretching means the watch was worn hard. Patek straps are replaceable at service but original straps add value to vintage pieces.
