The Patek Philippe Ref 5167 Aquanaut is a 40 mm steel sports watch with an octagonal bezel, a raised-grid dial, and an integrated rubber strap. Replica versions run from basic quartz models to automatic builds that follow the case shape, dial texture, and date placement. Four details decide quality: case thickness, bezel bevel, dial embossing, and strap fit.
Is a Replica Patek Philippe Ref 5167 Good Quality?
What Defines the Ref 5167 Aquanaut?
Patek Philippe launched the Aquanaut line in 1997 as a steel sports watch with a younger look than the Nautilus. The Ref 5167 is the time-and-date model, and the 5167A-001 in steel with a black dial is the version most replicas copy.

The genuine watch measures 40 mm across and about 8.1 mm thick, with water resistance rated to 120 m. Inside sits the Caliber 324 S C, an automatic movement with a 45-hour power reserve and a sweep seconds hand.
That mix of a slim case, a textured dial, and a composite strap is what makes the 5167 hard to copy. A case that runs 2 mm thick changes how the watch sits on the wrist, and that shows.

Specs That Matter on a Replica 5167
Case and bezel
The case should be steel-finished with a rounded octagon bezel that carries both brushed and polished surfaces. Check the bevel where the bezel meets the mid-case. On cheap replicas this edge is soft or uneven.
- Width: 40 mm
- Thickness: 8.1 mm on the original, 8.5 to 10 mm on most replicas
- Lug-to-lug: about 47 mm
- Crystal: sapphire on mid and top tiers, mineral glass on entry models
Dial and hands
The dial carries a raised grid pattern, often described as a checked texture. The print should be crisp, with the date window cut clean and the numerals centered.
Hands are baton style with lume fill. On weak replicas the fill sits uneven, the seconds hand stutters, or the date font looks too fat or too narrow.
Movement
Movement choice drives price and feel. Quartz models tick once per second. Automatic models sweep and carry a rotor you can see through the case back.
Strap
The strap uses composite rubber with a grid pattern that matches the dial. It cuts to size instead of using a buckle with holes. Most replicas ship with a spare strap or two.
Which Movement Options Show Up in Replicas?
- Quartz: Cheap, thin, and accurate. No sweep, no rotor.
- Japanese automatic (Miyota 9015): A workhorse with a smooth sweep and a 42-hour reserve.
- ETA 2824 or Sellita SW200: Swiss-made, serviceable, and found in the upper tier.
- Caliber 324 S C clone: Decorated to mirror the gen layout, including the gold-tone rotor.
Ask which movement sits inside before you buy. Two watches that look the same from the front can differ by hundreds of dollars because of the engine.
How Do You Check Quality Before Buying?
- Compare case thickness to the 8.1 mm original. Anything past 10 mm sits tall on the wrist.
- Study bezel bevels in photos taken from several angles.
- Zoom on the date window. Edges should be sharp, not ragged.
- Check the dial grid. It should stay even across the whole surface.
- Ask for a photo of the case back and clasp engraving.
- Confirm the strap texture matches the dial pattern.
Sellers who send fresh photos of the actual watch beat sellers who reuse stock images. Ask for a timestamped shot.
What Do Replica 5167 Versions Cost?
Entry models sit under $100 and use quartz or basic automatic movements. Mid-tier versions run $150 to $300 and add sapphire crystal and a Miyota movement. Top-tier builds with Swiss or clone movements run $400 and up.
Price tracks three things: movement, case finishing, and strap quality. A high price alone proves nothing, so match the cost against the parts list.
How Does the 5167 Wear?
The 40 mm case wears larger than the number suggests because the lugs curve down and the strap hugs the wrist. A 6.5-inch wrist handles it well, and it sits flat under a shirt cuff.
The cut-to-fit strap needs care. Measure before trimming, since you cannot undo a cut.
FAQ
Is the replica 5167 Aquanaut the same size as the original?
Most replicas hit 40 mm across. Thickness is where they differ, ranging from about 8.5 mm to 10 mm against the 8.1 mm original.
Does a replica 5167 have a working date?
Yes on most automatic versions. The date sits at 3 o'clock and changes at midnight. Quartz models also carry a date.
Can I fit a genuine strap to a replica 5167?
Sometimes, but the fit depends on the lug shape of each build. Measure the lug width and check the notch pattern before you spend on a gen strap.
How long does a replica 5167 automatic last?
A Miyota 9015 or ETA 2824 can run for years with basic care. Quartz models last until the battery dies, then need a swap.
