Short answer

IW329094 is an IWC reference in the Big Pilot's Watch 43 family. Replica IW329094 listings sell a copy of that watch: 43 mm steel case, large screw-in crown, black dial, date at 3 o'clock, leather strap or steel bracelet. Prices run from about $90 to $700. The movement sets the price. Most copies use a Chinese or Swiss automatic. Few copy the IWC calibre 82100.

IWC's public catalog should confirm the dial color and strap code for IW329094. I could not verify that code against IWC product pages. Treat the search as family-level: the Big Pilot's Watch 43.

What the original is

IWC Big Pilot's Watch 43. Case: 43.0 mm stainless steel, about 13.6 mm thick. Crystal: domed sapphire with anti-reflective coating on both faces. Crown: screw-in, fluted, oversized. Movement: calibre 82100, automatic, Pellaton winding, 60-hour power reserve, 28,800 vph. Soft-iron inner case for magnetic shielding. Dial: black, white numerals, Super-LumiNova on hands and markers. Date window at 3 o'clock. Strap: calfskin or steel bracelet.

Water resistance is listed per reference by IWC. Check the product page before you compare numbers. Copies are not pressure-tested.

Movement tiers in the replica market

  1. Entry, $90 to $180. Chinese copy of the ETA 2824, or a DG2813. Slow date flip. Rotor noise.
  2. Mid, $180 to $400. Seagull ST21, Hangzhou 6460, or a real ETA 2824-2 or Sellita SW200-1. 28,800 vph, roughly 38 hours of reserve.
  3. Top, $400 to $700. Clone of the IWC 82100 with Pellaton-style winding, or a decorated Sellita. The better clones reach 60 hours of reserve.

Ask for the movement name in writing. "Swiss movement" with no name means nothing.

Tells on the case and dial

  • Thickness. Copies run 14 mm to 15 mm against 13.6 mm on the original.
  • Crown. Original crown is about 8 mm wide and threads clean. Copies wobble or cross-thread.
  • Soft-iron inner case. Most copies skip it. A magnet test shows the gap.
  • Date disc. Check font, window position, and the jump at midnight.
  • Dial print and lume color. Replica lume is gray or green under a lamp. IWC lume is off-white.
  • Caseback. Reference and serial engraving depth. Laser etching looks flat.
  • Crystal. Sapphire gives a sharp reflection. Mineral glass scratches with a steel pick.

What to ask before you pay

  1. Movement make and model.
  2. Crystal material: sapphire or mineral.
  3. Case diameter and thickness in millimeters.
  4. Weight in grams.
  5. Water resistance test result, if any.
  6. Return window and shipping method.

Weight is the fastest filter. A 43 mm steel watch with a bracelet weighs about 120 g to 150 g. Copies land near 100 g.

Legal note

In the United States, importing and selling counterfeit watches violates trademark law. U.S. Customs and Border Protection can seize shipments. Buyers carry seizure risk and get no warranty. IWC does not service replica watches, and no Swiss brand does.
