Answer first
A replica of IW545114 is a copy of an IWC watch. A fake is that copy sold as a genuine IWC. IW545114 is an IWC Portugieser reference. No photo, listing, or box proves a watch is genuine. Check the movement, caseback engraving, dial print, serial, papers, and service record. Confirm the reference and serial with IWC or a watchmaker who services IWC. If the seller calls it an IWC and the price is far below market, treat it as a counterfeit until proven otherwise.
What IW545114 is
IWC reference numbers group a watch family and a case and dial variant. IW545114 sits in the Portugieser Hand-Wound line. Public listings describe a steel case near 44 mm, a hand-wound movement, small seconds at 6 o'clock, sapphire crystal, and a display back. Production runs and dial variants change details. Use the full reference and serial, not the family name, for a check. IWC service can confirm what left the factory.
Caseback and movement checks
Open the caseback only with a watchmaker. A genuine IWC movement has finishing, engraving, and component shapes that copies miss. Look at the balance bridge, jewels, screws, and ratchet wheel finish. The caseback engraving should be crisp and aligned. Reference and serial numbers should match the papers. A laser-etched or shallow engraving is a warning sign. So is a movement that does not match the hand-wound layout for the reference.
Dial, hands, and crystal
Check the dial print under a loupe. Letters should be sharp and level. Subdial spacing should match the reference. Hands should sit at the correct height and have clean edges. The crystal should fit the bezel without gaps. A date window, if present, should align with the dial opening. Photos on a phone hide print flaws. Use a 10x loupe and a straight-on light.

Papers, serial, and price
Papers are easy to copy. A card with a serial is not proof. Ask for the original invoice, service papers, and a dated warranty card. Call IWC or an authorized service center with the serial. Compare the asking price with sold listings for the same reference, condition, and box set. A low price is not proof of a fake, but it raises risk. A high price is not proof of a genuine watch.
Buying rule
Buy the seller before the watch. Use a written description that names the reference, serial, and condition. Pay with a method that has a dispute process. Meet a watchmaker for a check before you pay in full. If the seller refuses a movement check, walk away.
