A fake IW371422 is any IWC Portugieser Chronograph sold under that reference number that IWC Schaffhausen did not produce. The label covers two very different products: a low-grade counterfeit built to survive a phone photo, and a high-tier 1:1 replica built to match the genuine 40.9 mm case, dial layout, and chronograph functions.
What is the IWC IW371422?
The IW371422 sits inside the Portugieser Chronograph family, a 40.9 mm stainless steel watch with two vertical counters at 12 and 6 o'clock plus a small seconds subdial. The layout is unmistakable: elapsed minutes on top, running seconds below, slim feuille hands, and a thin railway minute track.
Earlier 3714-series Portugieser Chronographs ran on the 79320 calibre, a Valjoux 7750 base rebuilt and finished in Schaffhausen. That base matters for replicas, because a genuine 79320 has a specific rotor engraving, balance assembly, and pusher feel that most counterfeit movements never reproduce.
Why do people search for fake IW371422?
Two intents drive the search. One buyer has been offered a watch at a price that looks impossible and wants to know whether it is genuine or a counterfeit.
The other buyer already knows it is not an IWC and wants the closest visual match available. Those two people need completely different answers, and most pages online confuse them.
How do you tell a fake IW371422 from a genuine watch?
Dial, printing, and subdial geometry
Genuine dials use applied numerals and indices with polished edges, and the printing under a loupe stays razor sharp. Cheap fakes show flat stamped markers, fuzzy text, and subdials that sit slightly off centre.
Check the spacing between the two counters. On a real Portugieser the gap is even and the hands sweep without wobble.
Case, crystal, and finishing
The genuine case has crisp brushed flanks and polished bevels that meet in a hard line, not a soft blur. Genuine sapphire carries anti-reflective coating on both faces, which is why the dial almost disappears at an angle.
A counterfeit usually has single-side coating and a visible blue or purple sheen.
Movement and case back
Open the case back and you should see an automatic movement with a decorated rotor, Geneva stripes, and engraved IWC calibre text. A quartz tick, a plastic spacer ring, or an undecorated generic rotor ends the discussion immediately.
What separates a 1:1 replica from a cheap counterfeit?
- Case work: real 1:1 replicas replicate the 40.9 mm profile, lug curve, and case thickness within a fraction of a millimetre.
- Movement: a decorated automatic chronograph movement with a working 30-minute totalizer, not a faux subdial.
- Dial: applied numerals, correct font weight, and a properly finished sunburst or opaline surface.
- Crystal: sapphire, ideally with coating on both sides.
- Strap and clasp: alligator-grain leather and a signed deployant or pin buckle that matches the reference.
What should you check before buying a replica IW371422?
- Confirm the seller shows real photos of the exact watch, not stock images.
- Ask which movement is inside and whether the chronograph actually resets cleanly to zero.
- Request a close-up of the dial printing and the subdial alignment.
- Check the stated case diameter and thickness against the 40.9 mm genuine figure.
- Verify the return window and whether the watch is tested before shipping.
Frequently asked questions
Is a fake IW371422 worth buying?
A well-built 1:1 replica can be worth it if you want the Portugieser look and accept that it is not a genuine IWC. A cheap counterfeit rarely is, because the finishing and movement usually fail within months.
Do replica Portugieser chronographs keep accurate time?
High-tier automatic replicas typically run within about ten to twenty seconds a day when regulated. Quartz versions are more accurate but lose the sweeping chronograph hand and the correct pusher feel.
Can a watchmaker spot a replica IW371422?
Yes. A trained watchmaker identifies the movement architecture, rotor engraving, and dial finishing within minutes of opening the case back.
Does a fake IW371422 hold its value?
No. Replicas and counterfeits are consumer goods, not collectibles, so resale values are low and unstable. Genuine Portugieser Chronographs hold value far better because IWC services and authenticates them.
The short version
Judge a fake IW371422 on three things: dial finishing, movement quality, and case geometry. If all three match the genuine reference closely, you are looking at a serious 1:1 replica. If any of them falls short, you are looking at a counterfeit that will disappoint you in person.
