A fake IW371483 is a counterfeit copy of the IWC Portugieser Chronograph with a stainless steel case, silver-plated dial, and gold-plated hands. The quickest tells are the subdial layout (30-minute counter at 12, small seconds at 6), the case thickness, and the movement finish behind the sapphire back. A real IW371483 runs on IWC caliber 79350, a Valjoux 7750 base, and its case, movement, and papers share one serial number.
What is the IW371483?
The IW371483 is a stainless steel Portugieser Chronograph from IWC Schaffhausen, a two-register chronograph with a silver-plated dial. It belongs to the wider IW3714 family, which shares the case shape, the dial layout, and the movement base. IWC has built this line for years, so counterfeiters have had plenty of time to study it.
- Case: stainless steel, about 41 mm wide and about 12 mm thick
- Movement: IWC caliber 79350, automatic, based on the Valjoux 7750
- Subdials: 30-minute counter at 12 o'clock, small seconds at 6 o'clock
- Crystal: sapphire front and sapphire display back
- Dial: silver-plated with gold-plated hands and applied numerals
- Strap: alligator leather with a signed steel buckle
- Water resistance: 3 bar, which means splash resistance only
Dimensions and dial details shift between production years. Check the current IWC listing for your exact reference before you judge a watch.
How do you spot a fake IW371483?
Counterfeits fail on small details rather than one giant flaw. Work through the checks below in order, and bring calipers and a loupe if you can.
1. Subdial layout and spacing
The 79350 movement puts the 30-minute counter at 12 and the running seconds at 6. Many fakes use a cheap chronograph movement and force the subdials into those spots, which pushes them off-center or crowds them against the center pinion. Measure the gap between each subdial and the dial center. A visible mismatch means the watch is not original.
2. Case width and thickness
Replica cases run wider and thicker than the real thing, often by a millimeter or more. Extra thickness also pushes the crown out of line with the pushers. Calipers settle this argument in seconds.
3. Dial printing and logo
Original printing is thin, sharp, and level. Fakes show bolder type, ink bleed, or a logo that sits a hair off-center. Study the wordmark under the logo. A blurred or stretched line of text is a warning sign.
4. Hands and applied numerals
Genuine gold-plated hands have polished bevels and clean edges. Fake hands look flat, with rough sides or visible tool marks. Applied numerals on a copy show uneven gaps and patchy reflections.
5. Caseback engraving
IWC cuts the reference and serial number into the caseback with a deep, crisp line. Fake engraving looks shallow and uses the wrong font. On the display back, the rotor engraving and Geneva stripes on a fake are stamped, not finished.
6. Crown and pushers
A real crown turns with light resistance and no grit. Chronograph pushers click with a firm, short travel. Mushy pushers or a wobbling crown point to a cheap movement inside a cheap case.
7. Strap, buckle, and box
IWC ships this reference on an alligator strap with a signed buckle. Most fakes arrive with a generic leather strap, an unsigned buckle, and a box that copies the shape but not the print quality.
8. Serial numbers and paperwork
Case, movement, and warranty card should agree. Counterfeit sellers reuse the same serial across listings, so search the number you are handed. If it turns up on five watches for sale, none of them is real.
What do fakes get right?
Good copies nail the overall silhouette, so a photo taken from across a room tells you nothing. They also match the dial color and strap style well enough to pass a casual glance. The tells live in the details you only see up close: print weight, hand finish, movement decoration, and engraving depth.
Why are there so many fake IW371483 watches?
The Portugieser Chronograph is a clean, classic design, which makes it easier to copy than a complicated watch. Demand stays high and the price gap between genuine and fake is wide, so counterfeit workshops keep making it. Social marketplaces and classified sites let those watches reach buyers who have never handled a real one.
Where do fake IW371483 watches show up?
Most appear on social marketplaces, classified sites, and small shops that want crypto or a bank transfer. Listings borrow photos from auctions and real owners, which is why reverse image search helps. Pawn shops and flea markets turn up fakes too, often sold as estate finds with no papers.
How much does a fake IW371483 cost?
Most fakes sell in the low hundreds of dollars, and the better copies ask several hundred more. A genuine IW371483 trades in the thousands, new or used. That gap is the whole point: if the price looks too good, the watch is counterfeit.
Is it legal to buy a fake IW371483?
Buying or importing counterfeit goods is illegal in the United States and in most of Europe, and customs can seize the watch. You also get no warranty, no service support, and no resale value. Many repair shops will not touch a counterfeit movement at all.
FAQ about the fake IW371483
Can a watchmaker tell a fake IW371483 from the real thing?
Yes. A trained watchmaker spots the movement first, because the 79350 finishing and rotor engraving are hard to copy at low cost. Case size and dial printing confirm the call.
Does a fake IW371483 keep good time?
Some do for a while. Cheap chronograph movements lose accuracy over months, and the chronograph function on low-end copies often stops working. Service parts are not available anywhere.
Should I buy a fake IW371483 instead of a real one?
If you want the look without the cost, a homage or a microbrand chronograph is a safer buy. A counterfeit carries legal risk, no resale value, and no support.
How do I check an IW371483 before paying?
Ask for macro photos of the dial, caseback, movement, and serial, then confirm the number with IWC or an authorized dealer. Meet at a watchmaker for a hands-on check when the deal allows it.
Checklist before you buy
- Compare case width and thickness to the official spec
- Confirm the subdials sit at 12 and 6 with even spacing
- Inspect dial print, hands, and applied numerals under a loupe
- Read the caseback engraving and match the serial to the paperwork
- Check the movement finish through the display back
- Walk away if the price sits far below market
None of these steps needs special tools beyond calipers and a loupe. Ten minutes of inspection saves you from a costly mistake.
