A fake IW371495 is a counterfeit copy of the IWC Portugieser Chronograph reference IW371495, built with a generic case and a non-IWC movement, then sold with IWC logos and packaging. The real watch comes from the IW3714 family, a 41 mm chronograph line that counterfeiters target because the dial is clean and the design is easy to copy. You can expose most copies by checking four things: dial print, caseback engraving, chronograph feel, and movement finish.
Why the IW371495 gets copied so often
The Portugieser Chronograph has a plain, balanced dial. Two subdials, thin hands, and open space give a counterfeiter few details to fumble. That is the opposite of a complicated sports watch, where one wrong angle on a bezel insert gives the game away.
Demand adds to it. The IW3714 group has run for years with many dial colors and metal options, so a buyer who sees a slightly different dial may assume it is a variant rather than a fake.
What the genuine IW371495 should look like
Case, crystal, and dial
- 41 mm case with polished and brushed surfaces and sharp transitions
- Sapphire crystal with anti-reflective coating on both faces
- Two registers stacked at 12 and 6, with a date window at 3
- Applied markers or printed numerals that sit level with the dial surface
- Crisp, thin print on the logo and on the Schaffhausen text
Dial colors and case metals change between IW3714 runs. Confirm the exact variant for the reference you are looking at before you call a watch fake.
Movement
The IW3714 family uses two calibers: the older 79350, a reworked Valjoux 7750, and the newer in-house 69355. Both are automatic chronographs, and both show finishing that a clone cannot match.
How to spot a fake IW371495 in your hand
- Weigh it. A steel Portugieser Chronograph feels heavy for its size. Copies use thinner cases and lighter alloys, so the watch feels hollow.
- Look at the dial print with a loupe. Real IWC text has sharp edges. Fakes show rounded letters and uneven spacing.
- Check the subdial position. On a real dial the two registers sit on a center axis with equal gaps to the date window.
- Read the date font. Copies use wide, flat numerals that do not match the IWC typeface.
- Flip the watch. Caseback engraving on a genuine IWC cuts deep and clean, with the reference number, case number, and water resistance rating all legible.
- Press the chronograph pushers. Real pushers have firm, short travel and a clear reset snap. Cheap copies feel mushy, and the reset hand may not return to zero.
- Inspect the movement. Ask for photos with the rotor visible. A real caliber shows Geneva stripes, polished screws, and engraved IWC markings.
- Check the crown. A genuine crown turns with light resistance and screws down flush with the case.
Red flags in online listings
- A price in the low hundreds for a watch that should cost thousands
- Stock photos only, with no live shots of the actual watch
- No photo of the caseback or the movement
- Serial numbers blurred or described as polished off
- A new seller account with luxury watches and no history
- Pressure to pay outside a protected payment system
Fake, first copy, and super clone: what the labels mean
The replica market uses these terms as marketing, not as grades. A seller can call any watch a first copy and charge more for it.
- Budget copy: quartz movement, wrong case size, printed dial, plastic crystal
- Mid-tier copy: Asian 7750 clone, steel case, dial details that hold up from a distance
- High-end copy: case dimensions close to the real watch, decorated movement, closer fonts and hands
Even the best copy runs on a movement IWC never made. That gap is what a watchmaker spots first, and it is why a copy cannot be serviced by IWC.
What a fake IW371495 sells for
Counterfeit prices track the copy tier, not the original retail price. Budget copies sell for under $100, mid-tier copies run $150 to $400, and high-end copies ask $500 or more.
A genuine IW371495 sells in the thousands on the used market. Any listing that offers a new Portugieser Chronograph for a few hundred dollars is a fake, no matter how the seller explains it.
How to check a watch before you pay
- Get the full reference and serial from the caseback and match them to the paperwork.
- Ask for a video that shows the seconds hand moving and the chronograph starting, stopping, and resetting.
- Request clear photos of the movement with the caseback open.
- Ask for service records or the original dealer receipt.
- Have an independent watchmaker open the watch before money changes hands.
- Pay with a method that lets you dispute the charge if the watch turns out to be fake.
FAQ
Can a watchmaker tell if an IW371495 is fake?
Yes, and an open caseback makes it easy. Dial details narrow the field, but the movement decides. A watchmaker who has serviced a 7750 or an IWC caliber will know in seconds.
Do fake IW371495 watches use real movements?
No. They use Asian clones of the Valjoux 7750 or quartz modules. Some copies carry decorated movements from unrelated makers, but none carry an IWC caliber.
Does a fake IW371495 keep time?
A tuned clone can run within a few seconds a day, so timekeeping alone proves nothing. The weak points are parts, water resistance, and service, since no IWC service center will touch a counterfeit.
Will an IWC boutique authenticate a watch?
Service centers confirm authenticity during a service or repair. Most will not issue a standalone letter for a watch they did not sell, so a service quote is the practical path.
Bottom line
A fake IW371495 fails on the details a photo hides: weight, dial print, pusher feel, and movement finish. Buy from a seller who shows the caseback and the movement, and have a watchmaker look before you pay. If the price looks too low for a Portugieser Chronograph, it is not a bargain.
