Quick Answer
The IW371468 is an IWC Portuguese Chronograph, and the replica that gets closest to it copies four things above all: a polished steel case around 41 mm across, a slim profile near 13 mm, a two-register dial with running seconds at 6 and the chronograph minutes counter at 12, and leaf-shaped hands over applied numerals. The movement, the strap, and the case back are where the tiers separate. If a listing cannot show you a straight-on dial photo, a case back photo, and a short video of the movement running, do not send money.
Know the Reference First
Vetting a copy starts with the genuine article. Confirm the exact dial variant of the IW371468 against IWC's own catalog before you compare photos, because the Portuguese Chronograph line has run through several dial and movement combinations.
- Case: stainless steel, roughly 41 mm wide, about 12 to 13 mm thick, 20 mm lug width.
- Crystal: domed sapphire on the front, sapphire or engraved steel on the back.
- Dial: silver-plated or colored base, applied Arabic numerals, leaf hands, small seconds at 6, 30-minute counter at 12.
- Movement: either the older 79350, built on a Valjoux 7750 base, or the in-house 69355, depending on the production run. Find out which one your reference uses before you judge a replica's movement.
- Strap: alligator-grain leather on a signed pin buckle or deployant clasp.
How to Evaluate a Replica IW371468
- Ask the seller for caliper measurements of the case and compare them with the 41 mm figure, since copies under 40 mm sit noticeably small on the wrist.
- Study the dial in flat, shadowless light and check that both subdial centers sit on the vertical axis with no sideways drift.
- Count the applied numerals and markers, and confirm they are polished and raised rather than painted flat.
- Request a video of the chronograph start, stop, and reset, and watch whether the hands snap back to zero in one motion.
- Watch the small seconds hand at 6 for a smooth sweep, because the modified 7750 layout in many copies drives that hand through extra gears and can stutter.
- Inspect the crown and pushers for polish and flush alignment with the case band, then screw the crown in and out to feel for grit.
- Examine the case back engraving under magnification, and check that the reference number, caliber marking, and lettering are crisp.
- Confirm the strap, buckle, and spring bars match the listing, since sellers swap these parts to hit a price point.
Red Flags
- Only factory marketing images, with no real-world photos of the actual unit.
- A claim of a genuine Swiss ETA movement at a price that cannot cover one.
- Case backs with the reference number spelled wrong or the German name "Portugieser" missing.
- Subdial hands that are too thick, too long, or the wrong shape for the printed track.
What the Price Tiers Change
Entry copies use a basic 7750 clone with a rough finish and a stiff pusher feel. Mid-tier copies add a decorated movement, a sapphire crystal with proper anti-reflective coating, and better dial printing. Top-tier copies focus on case finishing, correct hand shapes, and a dial that holds up under a loupe. Spend your budget on the dial and case, since those are what people actually see on your wrist.
Before You Order
Replica watches are seized at the border in many countries, including the United States, so check the import rules where you live and treat any shipment as a risk. Ask about the return window in writing, and pay with a method that gives you a dispute path.
