Replica IW328064 watches circulate on resale sites, social marketplaces, and auction apps, and most are sold with paperwork that does not exist in the manufacturer's records. A counterfeit carries no IWC warranty, no service history, and no resale value, so the practical answer is this: buy from an authorized retailer, or buy pre-owned only after you verify the reference engraving, the movement, and the warranty card against the manufacturer's own records. The procedure below covers that check from first message to delivery.

Before you start

  • A loupe or a phone macro lens
  • Seller photos of the caseback, clasp, and warranty card
  • The asking price and the return window in writing
  • The reference number you expect to see: IW328064

Step-by-step verification

Confirm the reference

  1. Request a straight-on, well-lit photo of the caseback.
  2. Read the engraved reference between the lugs and compare it character by character with IW328064.
  3. Reject the sale if the digits differ, if the engraving looks lasered rather than cut, or if the seller cannot show it at all.

Check the dial and case

  1. Compare the dial layout, index shape, and hand finish with official press images for this reference.
  2. Look at the date window under magnification and confirm the font weight and alignment.
  3. Inspect the case flanks for machining marks and confirm the crown threads engage without grit.

Verify the movement

  1. Ask for a photo of the movement through the caseback if the model has a display back.
  2. Compare rotor engraving, jewel count, and finish with the caliber the manufacturer lists for this reference.
  3. Run the watch for 48 hours and check the rate against a timegrapher app before paying the balance.

Validate the paperwork

  1. Ask for a photo of the warranty card showing the dealer stamp, date, and serial.
  2. Call the dealer named on the card and confirm they sold that serial number.
  3. Walk away if the card is blank, undated, or printed rather than stamped.

Screen the seller and the price

  1. Compare the asking price with current pre-owned listings from established dealers.
  2. Ask the seller to confirm the watch is authentic in writing, with a return window of at least seven days.
  3. Pay with a method that offers buyer protection, never by wire or gift card.

On arrival

  1. Photograph the packaging and seals before opening.
  2. Have a watchmaker confirm the movement and case within the return window.
  3. Register the serial with the manufacturer to confirm the warranty position.
