Why people buy it
The Aquanaut is Patek Philippe's more casual sports watch, with a rounded octagonal case and a chequered dial matched by its 'tropical' strap. It is often seen as a younger sibling to the Nautilus.
What to check on a pre-owned Aquanaut
- Strap: the composite strap wears over time; ask about its condition and whether a spare is included.
- Reference: steel (5167A), gold and complicated versions are priced very differently. Check the reference.
- Dial: the embossed pattern should be crisp and match the strap.
- Fakes: buy from a dealer or marketplace that authenticates.
- Papers: Patek Philippe Certificate of Origin, box and service history.
- Serial: the movement and case numbers on the papers should match the watch.
