What is a replica IW371771?
A replica IW371771 is a third-party copy of the IWC Portugieser Chronograph reference IW371771, a 41 mm stainless steel automatic chronograph. Genuine versions sit in the mid four-figure USD range, so copies are produced to imitate the case, dial layout, and strap at a fraction of that price.
Quality splits into tiers. Budget copies use quartz movements and printed dials, while top-tier replicas use mechanical chronograph movements and closer case finishing. None are made by IWC Schaffhausen.

How close do replica versions get?
Movement
Most mechanical copies run on an Asia Valjoux 7750 variant or a Seagull chronograph movement rather than a 69355. That changes the pusher feel, the winding sound, and often the subdial spacing. A genuine 69355 has a crisp column-wheel start and stop with almost no button travel.
Case and dial
Case profiles on better copies are close in diameter but usually run slightly thicker. Dial printing is the fastest tell, because the railway minute track and the applied numerals at 12 and 6 lose sharpness on cheaper examples. Subdial hands are frequently a shade too short or too flat.
Crystal and finishing
Genuine sapphire has a clear, low-glare look from both sides. Many replicas use mineral glass or single-sided coating, which shows more reflection and scratches sooner. Bracelet and clasp finishing also separates tiers, since polished and brushed transitions are hard to fake cheaply.
How to check a replica IW371771 before buying
- Ask which movement is inside, then search that exact movement name for known faults.
- Request real photos of the actual watch, not catalog renders.
- Check pusher action on video, since a sticky reset points to a weak chronograph module.
- Confirm the return window and whether it covers movement defects.
- Compare the dial layout to the real reference, including the missing date window.
Are replica IW371771 watches legal to buy?
Laws differ by country, and in the United States selling or importing counterfeit trademarked goods is illegal. U.S. Customs and Border Protection can seize shipments of counterfeit watches, and reselling one as genuine carries real legal exposure. Buying for personal use sits in a grayer area, but the item is never a genuine IWC product.
Frequently asked questions
Does a replica IW371771 have a working chronograph?
Mechanical copies usually do, with a functioning start, stop, and reset. Quartz copies often run the chronograph hands as decoration only.
Is a replica IW371771 water resistant?
Treat any claim above 3 bar as unreliable. Gaskets on replicas are rarely tested, so keep the watch away from swimming and showers.
How much does a replica IW371771 cost?
Prices run from roughly 150 to 600 USD. Cost tracks movement type, case finishing, and crystal material more than any brand label.
