A fake IW371410 is a replica of the IWC Portugieser Chronograph, a 40.9 mm stainless steel watch with a silver dial and two subdials. The fastest way to tell one from the real thing is to check the movement, the dial printing, the feel of the crown and pushers, and the engraving on the caseback. Most fakes fail at least two of those four checks.
What are the real IW371410 specs?
The IW371410 sits in the Portugieser Chronograph 3714 family, a line IWC has sold in steel and precious metals since the late 1990s. These are the numbers you can confirm on the case, dial, and papers of a genuine watch:
- Case: stainless steel, 40.9 mm wide, about 12.5 mm thick
- Crystal: domed sapphire with antireflective coating on both faces
- Water resistance: 3 bar, which is splash protection, not swimming
- Movement: IWC caliber 79350 on most steel 3714 references, a reworked Valjoux 7750 with a 44-hour power reserve
- Dial: silver-plated with applied indices, chronograph minutes at 12, small seconds at 6
- Strap: alligator leather on a steel pin buckle
IWC changes small details between references, so match the number on the caseback to the exact spec sheet before you judge a watch.
How do you spot a fake IW371410?
Work through these checks in order. The first two take seconds, the last two need a loupe or a watchmaker.
1. The movement
Genuine 3714 chronographs run the 79350, a Valjoux 7750 base with IWC finishing and a signed rotor. Copies use a stock 7750, a Chinese clone of it, or a quartz module with a fake rotor glued on top.
Look through the display back where the reference has one, and confirm the rotor carries the IWC logo and the correct caliber number. A quartz tick on a watch sold as mechanical ends the conversation.
2. Dial printing and hands
On a real IW371410 the "IWC Schaffhausen" text stays sharp at 10x magnification and the subdial rings sit concentric with the center of the dial. Fakes show fuzzy serifs, uneven letter spacing, and rings that drift off center.
Check the date aperture and the applied indices next. Real indices sit level with even gaps, and the printed numerals line up on the same radius.
3. Crown, pushers, and winding feel
Winding a real 79350 feels smooth with light resistance through the whole turn. Cheap copies grind, and their pushers need a hard shove instead of a short click.
4. Caseback engraving
Genuine engraving is cut into the metal rather than etched on the surface. Reference numbers, the serial, and the "International Watch Co." script should look crisp with even depth across every letter.
5. Strap and buckle
IWC alligator straps have tight, regular scale patterns and a signed pin buckle. Fake straps feel stiff, and the stitching wanders along the edge.
6. Price, papers, and the seller's story
A steel 3714 in good condition sells for several thousand dollars used. A watch offered at a tenth of that price is a replica, and a seller who refuses to meet your watchmaker has answered your question.
How can you check a watch before you buy it?
- Ask for the reference and serial from the caseback, then compare them with IWC's records.
- Request macro photos of the dial, the movement, and the caseback engraving.
- Pay a watchmaker who services IWC for a written authentication.
- Use a payment method with buyer protection and avoid bank transfers to strangers.
- Meet at a boutique or an authorized service center when you can.
Are all fake IW371410 watches low quality?
No. The replica market has tiers, and the gap between a $60 street copy and a $400 super clone is wide.
- Budget copies: quartz or low-grade automatic movements, flat printed dials, hollow cases.
- Mid tier: a stock 7750, decent case finishing, dial flaws you can see under a loupe.
- High tier (1:1): a clone or genuine 7750 base, correct case dimensions, dials that pass a casual look but not a watchmaker's bench.
Even the best replica shows gaps in movement finishing, crystal clarity, and engraving depth. Know which tier you are looking at before you judge the price.
Frequently asked questions about the fake IW371410
How much does a genuine IW371410 cost?
New steel Portugieser Chronographs sell in the high four figures at retail, and used 3714 examples trade for less on the secondary market. Value moves with box, papers, and service history, so check current listings instead of old forum posts.
Can a watchmaker tell a super clone from a real IWC?
Yes. Movement finishing, rotor engraving, and the fit of the dial furniture give it away. A trained eye needs a loupe and a few minutes, not a full teardown.
Does a fake IW371410 keep time?
A replica built on a 7750 or a clone of it can keep good time once it is serviced. Quartz copies keep time too, but they do not sound or feel like a mechanical chronograph.
Is buying a fake IW371410 legal?
In the United States, importing and selling counterfeits is illegal and customs can seize the goods. Rules differ by country, so check local law before you buy or ship.
Match the reference number, the movement, and the price to the watch in front of you. Two mismatches out of three means you are looking at a fake.
