Short Answer

Replica IW327013 means a copy of an IWC Pilot's Watch reference in the Mark XVIII line. The real watch has a 40 mm steel case, a 20 mm lug width, 60 m water resistance, and calibre 35111 with a 42 hour power reserve. Copies sell for about $230 to $400. The reference number alone does not tell you the dial color or the strap. IWC gives each dial and strap pairing its own number, so confirm the build of IW327013 on iwc.com before you pay. If a dealer cannot name the dial color, walk away.

Numbers to Match

  • Case diameter: 40 mm
  • Case height: about 11 mm
  • Lug width: 20 mm
  • Water resistance: 6 bar, or 60 m
  • Movement: calibre 35111, Sellita SW300-1 base, 4 Hz, 25 jewels
  • Power reserve: 42 hours
  • Crystal: sapphire with anti-reflective coating
  • Magnetic shield: soft iron inner case

Two details catch most copies. First, the soft iron inner case. A copy with a Miyota 9015 and no inner shield weighs less than the real watch. Second, the crown. An IWC crown is signed and sits close to the case band, with no gap at the tube.

Movements Used in Copies

  • Miyota 9015: Japan, 28,800 vph, 42 hour reserve. Reliable. No decoration.
  • Seagull ST2130 or A2892: Chinese ETA 2892 copy. Thin rotor, smooth sweep.
  • Decorated 35111 copy: a Chinese movement with IWC style text on the rotor and bridges.

Ask for a photo of the movement and the rotor text. A listing that claims a Swiss ETA movement at $200 is not selling a Swiss ETA movement.

Factories Named for IWC Pilot Copies

Rep forums name MKS and V6F for IWC Pilot models. Other factories build IWC, and stock rotates. A factory name is not a quality grade on its own. Read the QC photos for the batch you are buying.

Price Bands

  • $80 to $150: quartz or low grade automatic, printed dial, wrong case height.
  • $230 to $320: Miyota 9015 or A2892, correct 40 mm case, clean dial print.
  • $320 to $450: clone 35111, better case finishing, closer crown and caseback engraving.

QC Checklist

  1. Dial text: letter spacing, font weight, and the position of the date window.
  2. Date: the Mark XVIII has a date at 3 o'clock and no day window. Check the wheel alignment.
  3. Hands: hour, minute, and second hand lengths against a real photo.
  4. Lume: apply a UV light. The tone should match the reference.
  5. Crystal: view it at an angle. Cheap coating looks milky.
  6. Caseback: engraving depth, and any special engraving if the reference carries one.
  7. Timegrapher: ask for rate, amplitude, and beat error numbers.

Red Flags

  • Dealer photos that match IWC press images.
  • No QC photos before shipping, or QC photos of a different watch.
  • Prices under $150 with a claim of a Swiss movement.
  • Listings that use photos of another Mark XVIII reference and call them IW327013.
  • No return window and no payment method with a dispute path.

Legal Note

Counterfeit watches are illegal to import and sell in the United States. Customs and Border Protection can seize a shipment, and the buyer loses the payment. 19 U.S.C. 1526 covers trademark counterfeits. A personal-use purchase still carries seizure risk.
