Patek Philippe
Aquanaut 5167A
5167A-001 · 40mm · 120m
Patek's casual sport on Tropical rubber.
Patek Philippe's two sport icons, 21 years apart
Nautilus came first, 1976, designed by Gérald Genta: the rounded-octagon bezel, integrated bracelet, and 'porthole' case construction came together as Patek's answer to AP's Royal Oak. The Aquanaut launched in 1997 as the casual, rubber-strap, more accessibly priced sister, designed for younger Patek buyers who wanted Patek-but-not-formal.

Same movement, different watches
Both run Cal. 26-330 S C: Patek's 4 Hz, automatic, 45-hour reserve calibre with sweep seconds and date. The horological content is identical. What you're paying for is case material, bracelet, and the brand-tier within Patek's hierarchy.
Genta heritage vs the casual offshoot
Nautilus carries the Genta design heritage and the integrated-bracelet luxury-sport prestige. Aquanaut is positioned as the modern, casual, rubber-strap counterpart, with the embossed-grid dial referencing the Nautilus's textured dial but pushed in a sportier direction.
Allocation reality
Both are allocation-only. Aquanaut 5167A waits are 3-5 years from Patek for first-time buyers. Nautilus 5811 in white gold is harder still: prior Patek purchase history is effectively required. Secondary markets reflect this: 5167A trades ~1.7x retail, 5811G trades ~1.7x retail consistently.

Verdict: which one?
If you want a Patek to wear casually: Aquanaut 5167A. Tropical rubber, 40mm, lighter wear; same movement as the Nautilus.
If you want the Genta-design Patek sport icon and you have the AD history: Nautilus 5811G. The white-gold integrated bracelet is the canonical Patek sport reference.
If neither is reachable: pre-owned 5712/1A or 5990/1A may be more attainable Patek sport options.
