Short answer
The Patek Philippe Aquanaut 5167A is a stainless steel sports watch with a 40 mm case, a composite rubber strap, and a self-winding movement. A replica of it is an unlicensed copy. Patek Philippe does not make it, does not sell it, and does not service it. In the US, trafficking in counterfeit watches violates 18 U.S.C. § 2320, and Customs and Border Protection can seize shipments at the border.
The genuine 5167A
- Reference 5167A-001. Steel case, 40 mm diameter.
- Movement: cal. 26-330 S C in watches made from 2019 on. Earlier examples use cal. 324 S C. Both are automatic.
- Water resistance: 120 m. Screw-down crown.
- Sapphire crystal front and back.
- Strap: composite rubber with a fold-over clasp.
- US retail sits near $25,000. Secondary market prices run above retail.
Patek lists the case at 40 mm. Thickness figures on dealer sites range from 8 mm to 8.5 mm, so treat any single number with care.
What "Swiss" means in the replica market
There is no grading body, no standard, and no registry for replica watches. Terms like "AAA" and "super clone" come from sellers, not from a factory standard. Most replica cases and movements are made in Chinese workshops. A "clone 324 S C" copies the layout of the caliber. It does not copy the materials, the hand finishing, or the tolerances.
"Swiss made" printed on a counterfeit has no legal basis. Swiss law limits that label to watches that meet Swiss content rules, and a counterfeit meets none of them. Ask for a movement photo before any purchase. Most listings show a stock image.
Where a replica differs from the original
- Movement: decoration and rate differ. Power reserve and accuracy are not comparable.
- Case: bevels, brushing, and lug shape show tool marks on most copies.
- Dial: print weight, lume color, and date font are the common tells.
- Strap: engraving on the clasp and the rubber texture.
- Water resistance: a claim on a listing, not a tested rating. Do not swim with a replica.
- Service: no parts network, no warranty, no repair path.
Legal status in the US
18 U.S.C. § 2320 sets up to 10 years in prison for a first trafficking offense involving counterfeit goods. Brand owners can also sue under the Lanham Act for damages and profits. CBP seizes counterfeit imports and destroys them. Marketplaces remove listings after takedowns by the brand.
Buying a counterfeit for personal use carries less exposure than selling, but the shipment can still be seized and lost. The seller takes the larger risk.
