A fake IW323746 is an unauthorized copy of an IWC watch stamped with that reference number. You spot it by checking four things: the caseback engraving, the movement inside, the dial printing, and the paperwork. IWC reference numbers use the IW plus six-digit format, and counterfeiters copy that format exactly, so the number alone never proves a watch is real.
What does the IW323746 reference number actually tell you?
An IWC reference broadly identifies the model family, case size, and case material. It does not identify the individual watch, which is why IWC also stamps a serial number on the caseback.
Replica makers print popular references onto fake casebacks because buyers search those exact numbers before purchasing. Treat the reference as a starting point, not as proof.
How do you spot a fake IW323746?
- Caseback engraving. Genuine IWC engraving is deep, crisp, and evenly spaced, including the words Probus Scafusia and Swiss Made. Fakes look shallow, laser-etched, or wavy, with wrong font weight and crowded lettering.
- Movement. Ask for a photo of the movement or have a watchmaker open the case. Genuine IWC automatics use in-house calibers with the Pellaton winding system and finely decorated bridges. Counterfeits hide generic ETA, Sellita, Seagull, or Miyota movements behind a decorated rotor.
- Dial and hands. Look at applied indices under magnification. Fakes show printing bleed, misaligned markers, uneven lume, and date wheels with the wrong font or window shape.
- Case and bracelet finishing. Genuine brushing and polishing transitions are sharp and consistent, and bracelet end links sit flush against the case. Fakes show soft edges, gaps, and a rattling clasp.
- Serial match. The serial on the caseback should match the movement and the warranty card. Mismatches are a red flag, and a factory service center can confirm authenticity.
- Price. A steep discount is the single strongest signal. If the asking price sits far below the market rate for that reference, assume counterfeit until proven otherwise.
Why are IWC references counterfeited so often?
IWC sits in the luxury tier where demand is high and case designs are clean and easy to copy. Counterfeiters target references that sell quickly on the secondary market and that buyers may not have handled in person.
Online listings make it worse, because photos can hide weak engraving and movements stay hidden behind a caseback.
Genuine IWC vs. high-end replica: what changes?
A high-end replica may look convincing at arm's length, but it fails on the details that matter over time. The movement is not serviceable by IWC, water resistance is unverified, and spare parts do not exist.
Genuine watches also hold resale value, while counterfeits lose most of their value the moment they are identified. That gap is the real difference between a replica and a fake sold as the real thing.
What should an authentic IW323746 cost?
Pre-owned steel IWC automatics in this range typically trade in the mid four figures to low five figures in US dollars, depending on year, condition, and whether box and papers are included.
Prices below that band, especially on a watch described as new, usually point to a counterfeit or a replica sold under false pretenses.
Frequently asked questions
Is IW323746 a real IWC reference?
The format matches IWC's reference system, but the reference alone does not confirm a specific watch. Confirm with IWC or an authorized service center before buying.
Can a jeweler tell whether an IW323746 is fake?
A trained watchmaker can usually tell by opening the case and inspecting the movement, engraving depth, and dial finishing. Jewelry staff without watch training often cannot.
Does a fake IW323746 keep good time?
Generic movements can run accurately at first, but they are rarely regulated well and are hard to repair. Accuracy is not proof of authenticity.
