What a replica IWC vintage watch is

A replica IWC vintage watch is a new watch built to look like an IWC reference made between 1939 and the 1980s. The copies follow five models: the Mark XI, the Ingenieur 666 and 666A, the Aquatimer 812AD, the Yacht Club 811, and the Portugieser 325. Prices run from about $80 for a quartz model to $400 or more for an automatic with a cloned Swiss-style movement. Every one of them is a modern watch. None contains vintage IWC parts.

The originals behind the copies

  • Mark XI. IWC supplied this pilot watch to the British Ministry of Defence starting in 1948. Calibre 89 came first, calibre 85 later. Case size was about 36 mm. A soft-iron inner case shielded the movement from magnetic fields.
  • Ingenieur 666. Introduced in 1955 with calibre 8531. Anti-magnetic construction. Reference 666A followed in 1967 with calibre 8541.
  • Aquatimer 812AD. IWC's first dive watch, from 1967. Internal rotating bezel and a screw-down caseback.
  • Portugieser 325. Dated 1939. It used calibre 74, a pocket watch movement, in a wristwatch case of about 41 mm.
  • Yacht Club 811. From 1967. An automatic sports model.

Where replicas and originals part ways

  1. Case size. Copies come in 40 mm to 42 mm. Originals from 1950 to 1970 came in 34 mm to 37 mm. A 41 mm "Mark XI" does not match any IWC case from the period.
  2. Crystal. Originals used acrylic. Copies use sapphire with an anti-reflective coating.
  3. Movement. Originals used calibres 74, 85, 89, 8531 and 8541, all mechanical, beating 18,000 or 19,800 vibrations per hour. Copies use Miyota 8215, Seagull ST19, ETA 2824 clones, or quartz.
  4. Lume. Original dials used tritium or radium. Both age to brown or cream. Copies use Super-LumiNova, which stays white and glows green or blue.
  5. Caseback stamps. Copy serial numbers do not appear in the IWC archive. Reference numbers are off by a digit on many examples.

Legal status in the United States

US law bars the import and sale of goods that carry a counterfeit trademark. Customs and Border Protection can seize shipments and destroy them. Selling a watch with an IWC logo that IWC did not make is trademark infringement. That is separate from build quality. A well-built copy is still infringing.

Service and resale

Independent watchmakers decline to service replicas in many cases. Parts for Miyota and ETA clones are sold by watch material suppliers. Resale value is close to zero. Original IWC vintage watches hold value because of serial records, original dials, and service history.

One note on numbers: published case diameters for vintage IWC references differ by year and by case maker. Measure a specific watch before you compare it to a copy.
