Short answer
IW328030 is an IWC reference number. IWC assigns a different number to each dial, case metal, and strap combination, so one watch can carry several references. Confirm the genuine model on iwc.com before you judge a replica against it. A listing that uses a reference number IWC does not publish is a warning sign.
Genuine specs for comparison
IWC lists these values for the Pilot's Watch Mark XX, the family that uses IW3282 references. Check the IWC product page for the exact number on the listing you are reading.
- Case: 40 mm stainless steel
- Movement: IWC calibre 32111, automatic winding
- Power reserve: 120 hours
- Water resistance: 100 m
- Crystal: sapphire with anti-reflective coating on both faces
- Dial: black with white printed numerals, date window at 3 o'clock

Case thickness, lug width, and bracelet options change between variants. A replica that matches one variant may not match another.
Movement
The genuine watch uses the IWC calibre 32111. Replicas use other movements. Common options are the Seagull ST21 series, a clone of the ETA 2824, and the Miyota 9015. Power reserve and beat rate differ from the genuine calibre. Ask for a clear photo of the movement and the rotor engraving before you buy. Sellers who cannot send one are a risk.
Tells to check on a replica IW328030
- Date font and date window position. Printed date wheels on replicas differ in weight and spacing.
- Dial print. Genuine numerals have sharp edges and even lume fill.
- Lume performance. Replica lume dims in under an hour in most cases.
- Crown logo depth and polishing.
- Caseback engraving, including the plane motif and the reference number.
- Bracelet end link fit and the strap change mechanism.
- Case weight and brushing direction on the lugs.
Questions to ask the seller
- Which movement is inside, and what is its power reserve?
- What is the case diameter and thickness in millimeters?
- Is the crystal sapphire or mineral glass?
- Can you send photos of the caseback and the movement?
- What is the return policy and the shipping method?
Price and legal risk
Replica prices for this reference run from about $90 to $600. Movement type, case finish, and bracelet quality drive the spread. The legal side is simpler. Importing counterfeit goods into the United States is illegal. U.S. Customs and Border Protection can seize the shipment, and the buyer can face civil penalties. Trademark owners can also pursue sellers. A replica is not the genuine watch and carries no IWC warranty or service support.
