A "replica" of the IW371633 is an unauthorized copy of the IWC Portugieser Chronograph reference IW371633, a stainless steel chronograph made by IWC Schaffhausen. IWC does not produce, license, or authorize replica versions of this reference, so any watch advertised as a 1:1 replica or super clone of IW371633 is a counterfeit, and making or selling one infringes the brand's trademarks in the United States and most other markets.
Fake Version of IW371633: What to Check Before You Buy
What reference IW371633 Actually Is
IWC reference numbers are structured, and the 3716 block belongs to the Portugieser Chronograph family. That means IW371633 is a chronograph in a round case with two subdials, a tachymeter-style dial layout, and a leather or steel bracelet depending on the version. Dial colors, indexes, and strap options differ between releases, so the exact specification for IW371633 should be confirmed against IWC's own catalogue rather than a seller's listing.
- Brand and line: IWC Schaffhausen, Portugieser Chronograph
- Case material: stainless steel in the standard versions
- Function: column-wheel style chronograph with two registers
- Production: authorized dealers and IWC boutiques only
Why the Phrase "Replica of Fake IW371633" Appears in Search
Buyers often type both words together because listing sites use them interchangeably. Sellers describe a counterfeit as a replica, a clone, or a mirror, and they add the word fake so the page matches more queries. This wording is a marketing device, not a quality grade. There is no official tier system, no factory certification, and no reference database for counterfeit IW371633 watches, which is why the descriptions vary from listing to listing.

How to Tell a Counterfeit IW371633 From the Genuine Watch
Counterfeit chronographs usually fail on the details that are expensive to reproduce. Check these points against official photography:
- Subdial spacing. Genuine Portugieser chronographs place the registers at 12 and 6 with even spacing from the center pinion. Copies often shift them or use a smaller diameter.
- Dial printing. Look at letter spacing in the brand name and the sharpness of the index edges under a loupe. Counterfeit printing looks soft or slightly thick.
- Pushers and crown. Genuine pushers sit flush with the case band and start and stop crisply with no lateral play.
- Caseback engraving. Reference numbers, case numbers, and hallmarks should be laser-sharp and consistent in depth.
- Papers and packaging. A genuine watch comes with a warranty card that matches the case number, plus the correct box for its production year.
- Movement behavior. A sweeping chronograph second hand that stutters at engagement is a common sign of a cheap modular movement.
Legal and Practical Risks
Counterfeit watches are seizable goods. U.S. Customs and Border Protection can confiscate shipments of counterfeit merchandise, and trafficking in counterfeit goods carries civil liability and, in serious cases, criminal penalties. Beyond the legal exposure, a counterfeit IW371633 has no manufacturer warranty, no service network, and no resale value once the finish wears. Repair shops often decline to work on counterfeit movements because replacement parts do not exist.
Better Ways to Get the Same Look
If the goal is the Portugieser aesthetic rather than the specific reference, several legitimate routes exist. Pre-owned IWC Portugieser Chronographs appear regularly on the secondary market, and the reference can be verified through the brand's archive or an authorized service center. Lower-cost alternatives from established watchmakers offer steel chronograph cases, two-register dials, and leather straps at prices far below a counterfeit's long-term cost. Buying genuine also keeps the watch serviceable, insurable, and resellable.
Quick Checklist Before You Buy Anything
- Confirm the reference number against IWC's official catalogue.
- Ask for the case number and match it to the warranty card.
- Compare dial photos to genuine listings side by side.
- Request a movement photo or a service invoice for pre-owned pieces.
- Walk away from any listing that uses the words replica, clone, or mirror.
