Short answer: PAM 90 is the Panerai Luminor Marina Automatic, a 44 mm steel watch with a black sandwich dial, small seconds at 9 o'clock, a date at 3 o'clock, and the ETA 7750 based OP III movement. Replica versions copy the outline. They do not match the case, dial, movement, or finish. Counterfeit watches are illegal to sell or import in the United States.

The genuine reference

  • Case: 44 mm brushed stainless steel, Luminor cushion shape with integrated lugs.
  • Crown guard: the Luminor bridge and lever, the signature part of the model.
  • Water resistance: 300 m.
  • Movement: OP III automatic, built on the ETA 7750 architecture, 28,800 vph, about 42 hours of power reserve.
  • Dial: black sandwich construction, Arabic numerals at 12 and 6, baton markers on the rest of the dial, small seconds at 9, date at 3.
  • Crystal: sapphire. Case back: screw down and solid.
  • Strap: 24 mm lug width, leather from the factory.

What replicas get wrong

Copy makers work from photographs. Parts that show in photos get attention. Parts that do not get less.

  • Movement: many copies use Asian automatic calibers such as the Seagull ST25 or Hangzhou 6 series. Some sellers advertise a Swiss ETA with no service record and no paperwork.
  • Dial: the sandwich layers sit at the wrong depth. Lume color drifts toward green or orange. Date font and date window size differ from the original.
  • Crown guard: the lever has rough edges and a weak spring. It may not seal.
  • Crystal: mineral glass on low tiers, sapphire with the wrong antireflective coating on mid tiers.
  • Case: alloy or plated brass on cheap units. A steel original weighs more.
  • Case back: engraving font, spacing, and depth of the reference numbers differ.

Legal status in the US

18 U.S.C. 2320 makes trafficking in counterfeit goods a federal crime with prison terms and fines. US Customs and Border Protection seizes counterfeit watches at ports of entry. Personal import of counterfeit items is not permitted. Sellers also face civil claims under the Lanham Act. A buyer gets no manufacturer warranty, no service network, and no resale market.

How to spot a counterfeit PAM 90

  • Ask for a movement photo. The PAM 90 has a solid case back, so the movement is not visible from outside.
  • Test the crown guard lever. The original snaps and holds its position.
  • Compare the case back stamp. The reference is PAM00090.
  • Check for the original invoice, box, and service record. Their absence is a warning sign.

Cost of a real PAM 90

Panerai no longer lists the reference, so it trades on the secondary market. Price tracks condition, box and papers, and service history. Check current listings instead of a fixed figure.
