Short answer

IWC does not list a reference IW329049 in its public catalog. The Mark XVIII pilot watch sits in the 3290 family. Documented references include IW329001, IW329002, IW329003, IW329004 and IW329005. Sellers who use the number IW329049 sell a 40mm Mark XVIII style pilot watch. Ask for a photo of the case back and a photo of the dial before payment. If the seller cannot show both, treat the listing as unverified.

Numbers the replica copies

  • Case diameter: 40mm
  • Case height: 10.8mm on the IWC original
  • Lug width: 20mm
  • Crystal: sapphire with anti-reflective coating on both faces
  • Water resistance: 6 bar, equal to 60m
  • Dial: matte black, white indexes, triangle with two dots at 12
  • Date: window at 3 o'clock, black disc, white numerals
  • Movement: IWC Calibre 35111, 25 jewels, 28,800 vph, 42 hours

Movements inside replicas

Three movements appear in 40mm Mark XVIII replicas. The Miyota 9015 runs at 28,800 vibrations per hour with 24 jewels and 42 hours of reserve. The Seagull ST1812 and the 2892 clone run at 28,800 vph with 21 to 25 jewels, depending on the version. Some builders fit a genuine ETA 2892-A2, which raises the price. Check the beat rate with a timegrapher app. A reading of 21,600 vph, or 6 beats per second, means the watch holds a cheaper movement than the listing claims.

Points to inspect

  • Crystal edge: a blue or purple tint at the rim points to single-sided AR coating. The original carries coating on both faces.
  • Date font: compare the numerals 3 and 8 against a photo of the original disc.
  • Crown: check thread engagement and stem length. Stripped crowns are the most common failure on this case.
  • Lume: the original uses Super-LumiNova. Replicas range from bright green to weak grey.
  • Case back: engraving depth and font weight. Shallow laser etching marks a low tier build.

Price tiers

Entry replicas of the 40mm Mark XVIII sell for USD 120 to 250. Mid tier builds with a Miyota 9015 or a decorated 2892 clone sell for USD 300 to 500. Listings above USD 600 claim 904L steel and a cloned 35111. Ask for the steel grade in writing. Grade 316L and grade 904L look the same in a photo. Head weight runs between 60g and 75g, so a scale reading separates a steel case from a plated brass case.

Legal position

Counterfeit watches are illegal to import into the United States under 19 U.S.C. 1305. Customs and Border Protection can seize a shipment, and the buyer holds no claim against the carrier. Selling a replica exposes the seller to trademark claims from Richemont, IWC's parent group. IWC does not service or warrant replica watches. Resale value sits near zero, and no authorized repair center will take the movement.
