What is a fake IW371768?
A fake IW371768 is a replica of the IWC Portugieser Chronograph reference IW371768, built to imitate the 41 mm steel chronograph with a vertical two-register dial. Replicas copy the case silhouette, dial printing, strap and packaging, but they rarely match the genuine watch's in-house movement, finishing or heft.
Most people searching this term fall into two groups: buyers who want to avoid paying genuine money for a replica, and buyers comparing replica quality tiers before ordering one.
How can you tell a fake IW371768 from a real IWC?
Compare the dial first, because printing and subdial geometry are where replicas fail most often. The genuine Portugieser Chronograph uses thin, crisp Arabic numerals with a stepped flange, and its two subdials sit on a strict vertical axis with even spacing above and below the pinion.
Then check the case profile and crown. Genuine cases measure roughly 41 mm across and about 13 mm thick with softly curved lugs, while many replicas run thicker, wear taller on the wrist, and use a crown that feels loose or gritty when wound.
Dial and printing tells
- Numerals look too bold, too rounded or unevenly spaced on replicas.
- Subdial rings sit too close to the pinion or overlap the running seconds track.
- Date window edges are sharp and unfinished instead of beveled.
- Hands are flat stamped steel rather than polished, faceted leaf shapes.
Case, caseback and strap tells
- Engraving on the caseback is shallow, blurry or the wrong reference text.
- Sapphire crystal shows a strong purple or blue tint at the edges.
- Strap leather feels stiff and plasticky, and the buckle logo is stamped rather than debossed cleanly.
- Case and bracelet show tool marks or uneven brushing near the lugs.
What movement is inside a replica IW371768?
Genuine examples use IWC's in-house calibre 69355, a column-wheel chronograph with a 46-hour power reserve and a decorated rotor visible through the display back. Replicas usually run a Chinese or Japanese substitute such as a Seagull ST19, a modified 7750 clone, or a quartz module in cheaper builds.
A quick function test helps: on a genuine column-wheel chronograph the pushers feel smooth and the chronograph seconds hand starts without a jump. Most replicas snap or hesitate.
Replica IW371768 quality tiers
- Budget tier: quartz movement, mineral glass, printed dial, wrong case thickness.
- Mid tier: automatic chronograph movement, sapphire glass, closer dial printing, correct-ish dimensions.
- Top tier: 1:1 case dimensions near 41 mm, sapphire with anti-reflective coating, decorated rotor, genuine-style strap and clasp.
Price tracks these tiers closely, so a listing priced far below the going rate for a given tier is usually a lower build with upgraded photos.
What should you check before buying a replica IW371768?
- Ask for the exact case diameter and thickness in millimeters, not "approx 41 mm".
- Request real photos of the dial at an angle to judge printing and hand finishing.
- Confirm the movement type and whether the chronograph is functional or decorative.
- Check the return window and whether the seller accepts a refund for wrong specs.
- Verify whether the seller shows the actual watch or stock images from someone else.
Is buying a fake IW371768 legal?
Trademark law in the United States and the European Union treats counterfeit watches as illegal to import, sell or distribute, and enforcement varies by country for personal purchases. Customs can seize replica shipments, and a replica carries no manufacturer warranty or service support.
