The IW371475 is the reference number of a stainless steel IWC Portugieser Chronograph with a silver-plated dial, gold-plated hands, and a black alligator strap. A fake IW371475 copies that look for a fraction of the price. The gap against the genuine watch shows up in three places: the chronograph movement, the case finishing, and the dial printing.
What Is the IW371475?
IWC builds this reference in a 41 mm steel case with a two-register chronograph layout. The dial carries subdials at 12 and 6 o'clock, a date window at 3, and applied gold-plated markers.
The shape traces back to the 1998 Portugieser Chronograph, a model the brand has sold in many dial colors and metals since.
- Case: stainless steel, 41 mm wide, about 13 mm thick
- Dial: silver-plated, two subdials, date at 3 o'clock
- Movement: calibre 69355, an in-house automatic chronograph with a 46-hour power reserve
- Strap: black alligator leather on a steel pin buckle
- Glass: sapphire front and back on current production
What Does "Fake IW371475" Mean in Practice?
The word "fake" covers two different products. One is a replica, a watch built to look like the IW371475 and sold as a replica. The other is a counterfeit, a replica passed off as the real thing to a buyer who pays genuine money.
The second type causes the legal trouble. In the US, importing or selling a watch that carries the IWC name and logo without a license breaks trademark law, and Customs can seize the shipment.
The term "first copy" shows up in listings as a quality label, not a legal category. The law looks at the logo, not the wording.
How Do You Spot a Fake IW371475?
Start with the movement, then work outward. Cases and dials on good replicas come close. Movements do not.
1. Check the Movement Through the Caseback
Current production of this reference has a clear caseback, so the calibre 69355 sits in view. Look at the rotor finish, the engraving, and the shape of the bridges. Replicas show a plain rotor, stamped text, or a third-party chronograph movement that does not match the reference.
Then press the pushers. A genuine chronograph starts and stops with a crisp click and resets with one snap. A weak or slow reset points to a cheap module.
2. Study the Dial Printing
Applied markers on the genuine watch have polished edges that catch light and throw a small shadow. Printed markers sit flat and dull. Text under 12 o'clock should be sharp and level, with even spacing between letters.
Check the subdials for centering. On fakes they sit a hair off, and the concentric rings inside them look coarse.
3. Inspect the Case and Crown
Genuine case work alternates brushed sides with polished bevels, and the lug edges stay sharp. On replicas, the lug edges feel rounded and the two finishes blur into each other. Crown engraving looks shallow on most copies.
4. Weigh It and Feel the Strap
A 41 mm steel chronograph has heft. If the watch feels hollow, treat that as a warning sign. Genuine alligator has an irregular scale pattern that changes across the strap; embossed cowhide repeats the same shape over and over.
5. Match the Numbers
The caseback reference and serial numbers should match the warranty card and the listing photos. One serial number appearing on many listings is a common tell.
What Do Replicas of the IW371475 Get Right?
Better replicas match the footprint, the strap width, and the general dial color. Across a table, the silhouette reads correct. Under a loupe, the gaps appear.
- Size and lug shape: close on mid-range and high-end copies
- Dial tone: close on silver-plated versions, though some fakes lean gray
- Movement: the widest gap. Replicas use third-party chronograph movements, not calibre 69355
- Finishing: hand-polished bevels and bridge decoration are rare on a fake
- Value: replicas sell for a small share of the genuine price and do not hold value
Is a Fake IW371475 Legal to Buy in the US?
Buying a counterfeit watch inside the US is a gray area for the buyer. Selling one is not. Trademark owners can pursue sellers, and Customs can destroy shipments that carry a copied logo.
If you want the look without the legal risk, a homage chronograph from a brand that does not copy the IWC logo is the safer route.
FAQ
Can a watchmaker tell a fake IW371475 from the real one?
Yes, and fast. A watchmaker opens the case, sees a movement that is not calibre 69355, and the question ends there.
Is a fake IW371475 worth buying?
It depends on what you want. If you want the look for daily wear and you accept that the movement is not IWC, a replica can do that job. If you want an heirloom and a serviceable movement for decades, a replica fails both tests.
Does a replica IW371475 hold resale value?
No. Replica prices drop the moment you wear the watch. Genuine IWC chronographs hold value better, though no watch is a guaranteed investment.
What is the difference between a first copy and a fake IW371475?
Both copy the design. "First copy" is a seller's label for a higher grade replica with better case work and a closer dial. "Fake" is the broader term buyers use for any watch that copies the reference.
How much does a genuine IW371475 cost?
Genuine examples sell for thousands of dollars on the secondary market, and replicas sell for a small share of that. Prices move with condition, box, and papers, so check current listings rather than trusting one figure.
Do replica Portugieser chronographs keep time?
Most run, and some keep good time for years. Service and parts are the weak point, since many replica movements have no supply chain behind them.
