The common synonyms for a fake IW371621 are "replica IWC Portugieser chronograph," "super clone IW371621," "IWC 3716 rep," "1:1 Portugieser," "mirror quality," and, for unbranded lookalikes, "homage." Sellers rotate these terms to slip past search filters and brand takedowns, so the same watch can appear under five names in one week. The label a listing uses tells you more about price tier and factory than any studio photo does.
What does each synonym for a fake IW371621 mean?
- Replica / rep. A watch built to mimic the IW371621 and sold with IWC markings. Quality runs from a $90 street-market piece to a $600 clone.
- Super clone. A marketing label for the top tier: clone movement, correct case height, etched dial details. No factory publishes specs, so the term means whatever the seller wants it to mean.
- 1:1, mirror, AAA+. Grade labels from the early forum era. They describe nothing you can verify in a photo.
- Homage. A legal lookalike with no IWC name on the dial. Several microbrands build Portugieser-style chronographs for $100 to $250.
- Franken. A replica fitted with a few genuine parts, often a crown, strap, or clasp, on a clone case.
Why one watch carries five different names
Brand owners file takedowns against the word "replica" and against the reference number itself. Sellers answer by scrambling both: "IWC 3716," "IW371621 chrono," "Portugieser style 41," "P. chrono bi-compax." Anyone searching for a fake iw371621 synonym is, in practice, hunting those aliases.
Payment processors scan listing text too. A page that says "homage" clears a card gateway that flags "super clone." That is why the same seller runs two storefronts with two vocabularies.
What the genuine IW371621 is
The IW371621 belongs to the IWC Portugieser Chronograph family: a 41 mm line with a bi-compax dial, a 30-minute counter at 12, small seconds at 6, and a date at 3. Recent steel versions run the in-house calibre 69355 behind a sapphire caseback, and IWC lists them in the high four figures. That price gap is the whole reason a replica market exists for this reference.

Price tiers for a fake IW371621
- Under $100: quartz or low-grade automatic, printed dial, wrong subdial spacing, case 2 mm too thick.
- $150 to $300: Asian 7750 automatic, decent case shape, soft dial print, wrong date font.
- $350 to $700: modified or clone 7750, correct 41 mm dimensions, applied markers, sapphire crystal.
- $700 and up: "super clone" territory. Ask for a movement photo and a caseback shot with a ruler in frame before sending money.
How to check a listing before you pay
- Compare the subdial positions at 12 and 6 against a photo from iwc.com. Clones often sit the counters too far apart.
- Ask for the case height. The real watch measures about 13 mm, and thin replicas hide that number.
- Request a close shot of the caseback engraving next to a ruler.
- Ask which movement drives the chronograph. A 7750-based clone uses a cam-and-lever setup, while the IWC calibre is a different architecture, so pusher feel gives it away.
- Watch a video of the running seconds at 6. A ticking hand means quartz inside a mechanical case.
- Check dial text with a loupe or zoomed photo. Fuzzy "Schaffhausen" lettering is the fastest tell on a $200 fake.
Legal and practical risk
US Customs and Border Protection can seize counterfeit watches at import, and a buyer has no recourse when a parcel vanishes in transit. Counterfeit watch sales also tie into organized crime networks tracked by the OECD and EUIPO. Beyond the law, resale is rough: replica forums price used pieces at half the purchase price or less.
Frequently asked questions
Is a super clone better than a 1:1 replica?
The terms overlap and neither is regulated. Judge the watch by movement photos and measured case dimensions, not by the label in the title.
Does a fake IW371621 hold value?
No. The reference number carries no collector premium on the replica side, and demand drops the moment a newer factory batch appears.
Can a watchmaker service a fake IW371621?
Often yes. A 7750 clone takes standard ETA-pattern parts, so many independent shops will work on it. A custom clone movement may leave you shipping the watch back to the seller instead.
What is the closest legal alternative to an IW371621?
A Portugieser-style homage chronograph from a microbrand costs $100 to $250 and carries its own name on the dial. You lose the branding and keep the look.
Bottom line
Search any of these synonyms and you will land on the same handful of factories selling the same watch under different names. Focus on the movement, the case height, and whether the seller will send fresh photos, since those three things separate a wearable clone from a $90 mistake.
