Short answer

IW329040 is an IWC Pilot's Watch reference in the Mark XVIII line. The genuine watch has a 40 mm stainless steel case, a black dial with white Arabic numerals, a date window at 3 o'clock, sapphire crystal, and an automatic movement. Replica versions copy the case, dial, and strap. They do not use an IWC movement. Most run a Miyota 9015, a Seagull ST2130, or an Asian clone of the ETA 2892.

Confirm the exact movement and dimensions on IWC's own product page before you compare listings. Reference numbers in this family differ by dial color, strap, and market, and resale pages mix them up.

Genuine reference points

  • Case: 40 mm stainless steel, about 11 mm thick
  • Lug width: 20 mm
  • Crystal: sapphire, antireflective coating on both faces
  • Water resistance: 6 bar (60 m)
  • Movement: IWC caliber 35111, automatic, 28,800 vph, 42 hour power reserve
  • Dial: black, white numerals, luminous hands and markers, date at 3

IWC does not publish a parts catalog for every reference. If a number here does not match IW329040 on iwc.com, treat the IWC page as correct.

What replica makers change

  • Movement. An Asian 2892 or Miyota 9015 replaces the 35111. Beat rate may be 21,600 vph instead of 28,800.
  • Crystal coating. Single side coating is common. It reflects more light.
  • Lume. Paint glows for a shorter time and at lower brightness.
  • Case finishing. Brushed and polished transitions are softer.
  • Dial print. Numeral thickness and date font drift between batches.
  • Weight. Plated brass cases weigh less than steel.

Reading a listing

  1. Find the stated movement. "Swiss ETA" without a photo of the rotor means nothing.
  2. Ask for case diameter and thickness in millimeters.
  3. Request a photo of the date window at 3, 15, and 28.
  4. Compare strap and buckle markings against IWC photos.
  5. Get warranty and return terms in writing.

Price bands

Replica pilot watches sell from about $80 to $500. Units under $100 use quartz or a low-grade automatic. The $250 to $400 band buys a Miyota 9015 or a decorated Asian 2892 with a sapphire crystal. Nothing in that range matches a genuine IWC, which sells new above $5,000.

Legal status in the United States

Counterfeit watches are illegal to import and sell in the United States. 18 U.S.C. § 2320 covers trafficking in counterfeit goods. 19 U.S.C. § 1526 lets Customs and Border Protection seize and destroy shipments. Trademark owners can sue sellers for damages and profits. Buyers risk seizure of the goods and, in some cases, civil claims.
