The Patek Philippe Aquanaut needs no introduction. Despite being positioned as an entry-level sports model, it is one of the most sought-after and hardest-to-obtain watches from the Patek Philippe boutique today. While the well-known time-only 5167A represents the modern Aquanaut, astute collectors are increasingly turning their attention to the '90s model, the original 5065A, which is also the reference offered here.
Launched in 1997 to attract a younger audience, the 5065A was initially priced as an entry-level Patek Philippe in stainless steel and fitted with a rubber strap. Marketed as a luxury sports watch and a younger sibling to the Nautilus, it was not universally well-received at launch, as it was seen as challenging the traditionally elegant identity of Patek Philippe. With that being said, any big change always comes with its opposition, and the 5065A, being the first-ever Patek Philippe to sport a rubber strap, was no exception.
With the recent surge in appreciation for sports watches, the Aquanaut is viewed in a much different light today, and the original 5065A is now a key reference for any discerning Patek collector. Ultimately, the appeal lies in its historical significance, marking the genesis of the Aquanaut line and securing its place as a highly collectable model.
Aesthetically, the 5065A is a straightforward early Aquanaut, built around a 38mm stainless steel case that wears a bit more compact than current models. It features the signature “grenade” dial in black, defined by its embossed checkerboard pattern. This particular example is also fitted with a striking multi-link stainless steel bracelet, which is a less common configuration where the repeating links echo the dial’s visual geometry, giving the watch a more cohesive overall design.
Turning the 5065A over reveals the in-house, self-winding Patek Philippe Cal. 315 SC, displayed beneath a sapphire exhibition caseback. It features a 21-carat solid gold central rotor with excellent finishing throughout and offers a 48-hour power reserve on a full wind.
I am fairly certain you didn’t need to read all of the above to decide whether you love this Aquanaut 5065A or not. It remains one of the most in-demand contemporary Patek Philippe references today, and the perfect go-anywhere-do-anything watch. Our example here, equipped with an uncommon stainless steel bracelet with a hidden clasp, offers a slightly more integrated look that sets it apart from the usual rubber strap configuration. Needless to say, the Aquanaut 5065A represents a key milestone for Patek Philippe and remains a collectable classic.
