Quick answer

IW329087 is an IWC Pilot's Watch Automatic 41 reference. The genuine watch runs IWC calibre 32110, an automatic movement with a 72-hour power reserve and a 4 Hz beat rate. The case is stainless steel, 41 mm across. A replica copies the outside. The movement inside is a Miyota 9015, a Seagull ST21, or a Chinese automatic built to look like the 32110. No part inside a replica comes from IWC.

Genuine specs to compare

  • Case: stainless steel, 41 mm diameter
  • Crystal: sapphire with antireflective coating
  • Movement: calibre 32110, 21 jewels, 28,800 vph, 72-hour power reserve
  • Dial: black with white printed numerals and a date window at 3 o'clock
  • Lug width: 20 mm on the 41 mm Pilot's Watch Automatic case

IWC built more than one dial variant in the 3290 family. Check the seller's photos against the official IWC page for IW329087 before you pay. This guide does not assume a dial color.

How replica versions differ

Case shape and dial print are the two areas where good replicas get close. Differences show up in small details. Look at these points:

  • Dial print. Genuine numerals are crisp and level. Replica print sits heavier, and the Schaffhausen line runs long.
  • Date font. Genuine date wheels use a thin, tall font. Many replicas use a wide, bold font.
  • Hand finish. Genuine hands are polished on the top face and brushed on the side.
  • Caseback engraving. Depth and sharpness vary. Laser engraving looks shallow.
  • Rotor. A Miyota rotor does not match the IWC 32110 rotor. Ask for a movement photo.

What to ask the seller

  1. Movement model and a photo of the movement.
  2. Case diameter and thickness, measured with a caliper.
  3. Crystal material. Mineral glass is a downgrade from sapphire.
  4. Water resistance. Most replicas carry no rating. Do not swim with one.
  5. QC photos of the dial, date wheel, crown, and caseback.

Price and risk

Replica prices run from about $150 to $600. The gap tracks the movement, the case finishing, and the crystal. A higher price does not guarantee a better watch. Ask for photos of the exact unit you will receive.
