What is the IW371432 and why do fakes of it exist?
The IW371432 refers to the IWC Portugieser Chronograph, a 40.9 mm steel watch with two subdials, a date at 3 o'clock and a chronograph movement built on the Valjoux 7750 layout. Fake versions copy the case shape, dial layout and printed logo, then sell for a fraction of the real price. Most come from a handful of Chinese factories that build cases, dials and movements as separate parts and assemble them to order.
Does IWC make a reference called IW371432?
IWC's public catalog uses IW3714 plus two more digits for the Portugieser Chronograph line, and IW371432 is not a number that shows up in IWC's own reference lists. Treat "IW371432" as seller shorthand, not a confirmed catalog entry. The watch being copied is the standard Portugieser Chronograph, so every check below applies to that model.
What do replica listings for this reference claim?
Sellers push the same handful of claims for this model. Most of them fall apart under a loupe or a set of calipers.
- "1:1 clone" or "same as genuine" means the outside looks close in photos. Nothing more.
- "Swiss movement" in this price bracket means an Asian 7750 with a swapped rotor or a printed label.
- "Sapphire crystal and 316L steel" is often true, and it says nothing about build quality.
- "Full set with box and papers" means the box and warranty card came out of the same workshop as the watch.
How do you spot a fake Portugieser Chronograph?
Start with the case, then the dial, then the movement. Each step takes under a minute and each one catches a different class of fake.
Case size and thickness
The real watch measures 40.9 mm across and about 12.3 mm thick. Replicas built on an Asian 7750 run thick, often 13.5 mm or more, because the movement stack needs the room. Put calipers on the case and compare the number to the spec sheet.
Dial printing and applied numerals
On the genuine dial the "IWC SCHAFFHAUSEN" text sits crisp and level, and the applied numerals at 12 and 6 catch light along a sharp edge. Replica printing looks soft at 10x, with ink that bleeds and letter spacing that drifts. Check the minute track as well. Crooked markers are the fastest tell.
Subdial spacing and hands
The chronograph minutes sit at 12 and the running seconds at 6, and on the real dial both subdials sit close to the center line. Replicas built on a different movement base push the subdials outward or shrink them. Look at hand length too. Genuine hands reach the hash marks, while replica hands stop short.
Caseback, movement and engraving
Many Portugieser Chronographs have a display back, and that is where replicas lose the argument. Genuine IWC calibre finishing includes Geneva stripes, blued screws and a signed rotor. Replica movements show rough perlage, plain screws and a rotor with shallow engraving. Caseback text is another tell: replica fonts run wide and the stamped reference numbers do not match the model.
Crown, date and strap
The crown on the genuine watch carries a sharp, deep engraving of the IWC mark. Replica crowns use a shallow stamp that wears flat within months. Check the date window edge as well. Real windows sit flush with the dial, while replica windows cut a visible step.
What photos should you ask for before you buy?
Good photos settle most questions. Ask for these five, shot on a phone in daylight rather than in a studio.
- A straight-on dial shot, so you can check printing and marker alignment.
- A profile shot on a flat surface next to a ruler, to show real thickness.
- A macro of the caseback and any engraving.
- A focused shot of the movement through the display back.
- A close-up of the crown and the date window edge.
A seller who cannot produce these is hiding something, and that rule applies to genuine used watches as much as to replicas.
What are the risks of buying a fake IW371432?
The watch is the smallest part of the risk. Counterfeit goods carry legal exposure, no service path and no resale value.
- Legal exposure: trafficking in counterfeit goods is a federal crime in the US under 18 U.S.C. § 2320, and importing them can lead to seizure and penalties.
- Customs: CBP officers inspect and seize counterfeit shipments, and the buyer has no recourse when a parcel disappears.
- No service: authorized watchmakers will not touch a counterfeit, and parts for clone movements are not stocked.
- No resale: you cannot sell it as genuine, and selling it as a replica brings back the same legal problem.
- Seller fraud: many replica sites take payment and ship nothing, or ship a lower grade than the photos showed.
Questions people ask about the fake IW371432
Is a fake IW371432 worth the money?
Only if you want the look for a short time and accept that it has no resale value. A few hundred dollars for a replica of a watch that sells for several thousand new buys a costume, not an investment. Repairs on a clone 7750 cost more than the watch is worth.
Can a jeweler tell a replica Portugieser from the real one?
Yes, in seconds. Case thickness, dial printing and movement finish are all visible without opening the watch. Any watchmaker who services IWC will spot a clone movement from across the bench.
Do replica IW371432 watches use real IWC movements?
No. IWC does not sell its calibres to third parties, so a genuine 79350 or 69355 cannot end up in a replica case. Claims of a "Swiss ETA" inside a replica Portugieser are sales talk.
What does a real IWC Portugieser Chronograph cost?
New steel models list in the high four figures in US dollars, and pre-owned examples trade below retail depending on age and condition. Check IWC's site or an authorized dealer for current pricing, since it moves with each collection update.
What should you do instead?
If the Portugieser look is the goal, a used example from a dealer with references costs more than a replica but holds value and can be serviced. A chronograph from a mid-range brand costs less than a replica and arrives with a warranty. Either path leaves you with a watch you can wear without checking who is looking.
