A fake IW371408 shows itself in four places: case finishing, dial printing, bracelet fit, and the movement under the caseback. Real IWC Ingenieur Chronograph watches have sharp bevels, subdials that line up with the hand stack, and a rotor that winds with a soft, even click. A copy will fail at least two of those checks.
What Is the IW371408?
IW371408 is a reference number from IWC Schaffhausen's Ingenieur Chronograph family, a steel sports watch with a chronograph, a screw-down crown, and a metal bracelet. The line ran for years and produced many close variants, so reference numbers sit within a few digits of each other.
That matters for buyers. A copy often starts life as a different reference and gets sold as a 371408, which is why the caseback stamp and the paperwork deserve as much attention as the dial.
Confirm the specs (case size, crystal type, movement, bracelet taper) against IWC's own reference data before you judge any single watch.
How Can You Tell a Fake IW371408?
Work from the outside in. Cheap tells sit on the surface, and the hard ones hide behind the caseback.
1. Case and lugs
- Bevels: Genuine cases show a polished bevel that runs in one clean line along the lug. Fakes show rounded or wavy edges from a polishing wheel.
- Brushing: The brushed top surfaces should run in one direction and stop at a crisp line where the polish starts. On fakes, the two finishes bleed into each other.
- Crown: The crown logo should be centered, deep, and even. A shallow or off-center stamp is a common flaw.
- Weight: Steel cases feel dense in the hand. A hollow case points to cheaper alloy.
2. Dial and hands
- Printed text is the fastest test. Genuine dial print sits flat and sharp under a loupe. Fakes show soft edges, thick strokes, or ink that sits on top of the surface.
- Subdial spacing should be even and centered on the hand stack. Crooked or crowded subdials mean a rebuilt dial.
- Hands should reach the track they point at. Short hands that stop before the minute track are a giveaway on budget copies.
- Check the date window. An off-center date wheel is hard to fake.
3. Movement
Ask for a movement photo before you buy. Real chronographs in this family use a column of parts that a watchmaker can identify in seconds, and IWC engraving on the rotor is part of that picture. A blank rotor, glued-on decoration, or a quartz tick instead of a sweep points to a fake.
Listen, too. A mechanical chronograph winds with resistance and a fine click. A quartz copy stays silent until the second hand jumps.
4. Bracelet, clasp, and caseback
- End links should sit flush against the case with no gap and no rattle.
- Screws on the bracelet should be uniform and sit level with the link surface.
- Clasp engraving should be crisp and centered, with the correct reference and serial layout.
- The caseback reference stamp should match the model, and the digits should be cut, not printed.
What Do the Different Fake Grades Look Like?
Not every fake is the same watch. The market splits into three tiers, and each one fails a different test.
- Budget copies ($50 to $150): Quartz movement, plated case, stamped dial. They look wrong from a foot away.
- Mid-tier automatics ($200 to $500): Copy of a common automatic movement, correct case shape, weak dial print, soft bracelet fit.
- High-end copies ($600 and up): Close case finishing and a decorated clone movement. They pass a casual look but lose points under a loupe and on a timegrapher.
Prices move with the market and with the seller, so treat those bands as a guide, not a rule.
How Much Does a Fake IW371408 Cost?
Most fakes of this reference land between $80 and $700, and the gap tracks the movement, not the dial. A genuine Ingenieur Chronograph in steel sells for several thousand dollars on the used market, and no copy reaches that build quality.
If a seller offers a "new" IW371408 for a few hundred dollars and calls it real, the watch is a fake or the seller is lying. Both answers mean walk away.
Fake IW371408 FAQ
Can a jeweler tell a fake IW371408?
Yes, in most cases. A watchmaker with a loupe and a caseback opener can check the movement, the dial print, and the case stamp in a few minutes. Bring the watch in before you pay, not after.
Do fake IW371408 watches keep time?
Quartz copies keep good time and need a battery swap once a year or so. Automatic copies run about 20 to 40 seconds a day off when new, and drift more as the parts wear.
Are fake watches waterproof?
Do not trust the rating. Gaskets on copies are often missing or dry, so keep any fake away from water, showers, and pools no matter what the caseback says.
Does a fake IW371408 hold value?
No. A copy loses most of its resale value the moment it leaves the seller. Genuine references from this family hold value better, though servicing costs eat into that.
Buyer Checklist for a Fake IW371408
- Compare the caseback reference stamp with IWC's published data.
- Ask for a movement photo and a short video of the second hand.
- Shine a phone light along the lug and check the bevel line. Straight and sharp, or soft and wavy?
- Check the date window and subdial alignment.
- Slide a fingernail into the gap between the end link and the case.
- Price the watch against the tier list. A real Ingenieur Chronograph does not sell for $300.
Run those six checks and a fake IW371408 is hard to miss. A real one survives all of them.
