This replica aquanaut 5167A0 40.8mm represents the entry point into the Aquanaut collection and one of the most sought-after sport watches in the Patek Philippe catalog. The 5167A-001 measures 40.8mm in stainless steel with a black embossed dial displaying the chequerboard texture that defines this collection. Paired with a black tropical composite strap, the watch reads as modern and sporty without sacrificing the refined finishing expected from Geneva watchmaking. The 5167A became the accessible gateway to Patek sport watches after the Nautilus reached cult status.

Key Specifications

• Case diameter: 40.8mm
• Case material: stainless steel
• Dial: black with embossed chequerboard pattern
• Crystal: sapphire with anti-reflective coating
• Strap: black tropical composite rubber
• Movement: automatic with sweep seconds
• Functions: date, sweep seconds

The tropical composite strap resists UV exposure, saltwater, and temperature extremes, making it one of the more practical straps in the luxury segment. The fold-over clasp sits flush against the wrist without creating pressure points under the strap.

Design & Finishing

Where the Nautilus uses horizontal embossing, the Aquanaut chequerboard creates a grid-like relief across the dial surface. Applied luminous markers at each hour position contrast against the matte black background, and the hands feature a slim, polished profile. The 40.8mm case sits between the smaller Nautilus references and the larger chronograph variants, making it versatile enough for most wrist sizes. For a different take within the same family, the Travel Time 5164R-001 in rose gold adds dual time-zone functionality and a warmer case material. Both are part of the broader Aquanaut collection, but serve different daily-wear scenarios.

On the Wrist

The stainless steel 5167A wears lighter than its gold counterparts, and the rubber strap conforms to the wrist after a few days of regular use. The rounded octagonal case shape inherited from the Nautilus DNA makes it sit comfortably under a shirt cuff despite the 40.8mm width. This is the Aquanaut that most collectors start with before exploring Travel Time or chronograph variants. This replica aquanaut 5167A0 40.8mm gives you that same starting point with all the correct proportions and dial detail in place.
