Values & guides
A working dealer's guide to buying the Aquanaut, from the steel 5167 to the chronograph 5968 and the composite tropical strap.
Patek launched the Aquanaut in 1997 as a younger, sportier sibling to the Nautilus. It borrowed the rounded-octagonal case silhouette but added an embossed "tapisserie" dial and a composite tropical strap instead of a metal bracelet. For years it sat in the Nautilus's shadow. That changed over the last decade. The Aquanaut is now one of the hardest Patek sport watches to buy at retail, and demand at the secondary level has followed. It reads as a watch for people who already know what a Nautilus is and want something with more attitude.
The original 5060 measured a modest 35mm. The line grew through the 5065 and 5066, but the reference that defines the modern Aquanaut is the 5167, introduced in 2007 at 40mm. The 5167A is the steel version most buyers chase; the 5167R is rose gold on a matching brown composite strap, a warmer and more discreet option that trades for less than the steel in most markets.
In 2017 Patek added the 5168G, the so-called Jumbo, at 42.2mm in white gold. It arrived with a khaki-green dial that helped push olive and green tones into the spotlight across the collection. The 5164 Travel Time adds a dual-time complication with pushers on the left flank. The 5968 is the Aquanaut Chronograph, a 42.2mm watch first shown in steel with an orange accent, later in rose gold and white gold. Women's models live under the Aquanaut Luce name in smaller cases, often with gem-set bezels.
Know that the strap sizes you see quoted, such as 21mm or 22mm at the lug, refer to the composite band, not the watch case. A 5167R takes a 21mm brown strap; the larger 5168 and 5968 references use 22mm tropical straps in black, midnight blue, or olive green.
The Aquanaut bezel is fixed and polished, with no diving rotation. The signature is the dial: a raised grid pattern that grows larger toward the edges, paired with applied luminous numerals. Core dial colors are black, midnight blue, khaki-olive green, and on precious-metal pieces, brown. The 5968 chronograph dials add a contrasting subdial and date window.
The composite strap is a genuine part of the design, not an afterthought. Patek calls it tropical: a tough, skin-friendly polymer that resists water and aging far better than leather. Each color is matched to a dial, so an olive-green polymer strap belongs with a green-dial watch, midnight blue with blue, and brown with the rose gold 5167R. Straps wear out and are replaceable, and a fresh factory strap is an easy way to refresh a watch that has seen wrist time.
Start with the case lines. The Aquanaut mixes brushed and polished surfaces, and a sloppy polish destroys the crisp transition between them. Look for rounded edges or a cloudy bezel, both signs of overpolishing that no amount of cleaning fixes.
Confirm the strap and clasp match the reference and color scheme. Aftermarket straps are common and not disqualifying, but they should be priced accordingly. The folding clasp on later references is signed and should operate with a clean, even click.
Wind and set the watch. The 324 SC self-winding movement in the 5167 should run smoothly; the chronograph 5968 uses the CH 28-520 and its pushers should feel positive without mush. Date changeover near midnight is a quick health check. Always insist on the original certificate of origin and, ideally, the box and setting pin. Patek's Extract from the Archives can confirm production details for a fee, and an authorized service history adds real value.
The Aquanaut trades above retail for the steel sport references and closer to or below retail for some precious-metal and complicated pieces. Steel 5167A commands the strongest premium because production is limited and waitlists are long. Rose gold 5167R typically sells for less than steel, which surprises new buyers but reflects pure demand. The 5968 chronograph and the 5168G Jumbo occupy higher absolute price bands given their complications and gold content.
Three factors move price most: reference and metal, condition with full set, and current sentiment, which swings with the broader Patek sport market. Discontinued dial colors and early production runs carry collector interest. A complete watch with stamped warranty card, unworn or lightly worn, sits at the top of its band; a polished example missing papers sits well below it.
Treat any single quoted figure as a snapshot. Prices for this model have proven volatile, climbing sharply and then settling. Buy the specific watch in front of you on its merits, condition, completeness, and originality, rather than chasing a number you saw a year ago.
